Weekend HW = Take Your Experiment Notes!

Assignment Due Tuesday, January 7th:

• Your job is to take your own notes on experimental design!
• These are YOUR notes. Be thorough. We will discuss experimental design for 3 class periods with a quiz next Friday! The more thorough your notes, the better prepared you'll be!
• I will collect the (19) multiple choice questions at the start of class Tuesday; this will be graded as a quiz. Use your notes to help with these!

• Here's everything you need for the assignment:
• First, read chapter 13 and answer the questions linked below in your notes. (I also gave these to you in class on Friday).
• There is a link to a slightly newer version of our book on the blog (top right); you can use this to take your notes, but the page numbers listed may not match up.
• You don't have to write the question--do what works for you, these are your notes. Use bullets, use complete sentences, whatever works best for you.
• Try to avoid just copying stuff from the book; if you put ideas in your own words it makes you think about what you're writing, and ultimately develop a better understanding
• Jot down any questions that come up--for instance, if you don't understand what a "confounding variable" is, make a note of that! Your questions will guide our discussions in class.
• Chapter 13 Reading Questions (Guided Notes) Click Me!
• Question 7: .
• 7.) An experiment is the ONLY method of data collection that allows us to establish a cause and effect relationship.

• Then complete the multiple choice linked below (or provided by the sub yesterday):
• These questions are based on your notes/reading in chapter 13!
• These will be collected and graded as a quiz on Tuesday!
• Chapter 13 MC: Due Tues, 1/7 (Click Me!)

• Another helpful resource:
• The link below has answers to a bunch of questions students asked last year after their reading. If you were confused about anything you read, take a look here and you'll likely find some more info about that topic/idea!

• READ THIS!

Happy Winter Break!

#1 priority for break: rest up, relax, ENJOY some time with friends and family, and ENJOY some alone time too! Use this as an opportunity to "recharge your battery" and come back fresh in 2020! We'll be starting a new unit when we come back (chapters 12, 13 in our textbook--how do we collect data?); come ready to give your best and to perform your best in our second half of the year!

There will be an assignment due after our 3 day (Three Kings Day) weekend after break. All the info is below if you want to get ahead. If you want to use this week off as a true break, great! Or, if you're the kind of person who likes to get ahead, here's the deal:

Assignment Due Tuesday, January 7th:

• Our next unit is about how to collect data--how to design experiments, and how to randomly collect samples. However, you know lots about experiments already--so, to save time (and because you know lots of stuff), you will have to read chapter 13 in our textbook and take your own notes!
• Then we'll spend about 3-4 class periods applying what you learned and looking at some AP FR and AP MC.
• Here's everything you need. 
• First, read chapter 13 and answer the questions linked below in your notes. (I also gave these to you in class on Friday).
• There is a link to a slightly newer version of our book on the blog (top right); you can use this to take your notes, but the page numbers listed may not match up.
• You don't have to write the question--do what works for you, these are your notes. Use bullets, use complete sentences, whatever works best for you.
• Try to avoid just copying stuff from the book; if you put ideas in your own words it makes you think about what you're writing, and ultimately develop a better understanding
• Jot down any questions that come up--for instance, if you don't understand what a "confounding variable" is, make a note of that! Your questions will guide our discussions in class.
• Chapter 13 Reading Questions (Guided Notes) Click Me!
• Question 7: we haven't had our first day of notes yet! So here's the answer...
• 7.) An experiment is the ONLY method of data collection that allows us to establish a cause and effect relationship.

• Then you will have to complete the multiple choice linked below! I will give you this when we're back from break, but if you want to get even more of a head start, here you go!
• These questions are based on your notes/reading in chapter 13!
• Chapter 13 MC: Due Tues, 1/7 (Click Me!)

• Another helpful resource:
• The link below has answers to a bunch of questions students asked last year after their reading. If you were confused about anything you read, take a look here and you'll likely find some more info about that topic/idea!
• Common Questions After Reading (Answered) (Click Me!)

Are you feeling absolutely insane and realllly want to get ahead? 

• I think doing what's about is enough, but if you're super ambitious, here's some more ways to get ahead of the game:
• Start counting/organizing your stamps!
• Stamps will not be due until 1/15, but you can still start to organize them if you like!
• Same deal as last time--you'll have to count them up, get them all together, write the total on the front.
• Always double check your count.
• 
  

See ya'll in 2020! Come back ready to go! Have an awesome 12 days off!

STUUUUDDDDYYYYYYYYY!!!!

*Sorry to be a downer, but if you have Principal's Bingo tomorrow during period A it would be a terrible idea to miss our test for Principal's Bingo. If you have a free period you can come do your test later in the day, but otherwise I would skip Bingo and get your test done.

It's not break yet. Come ready tomorrow. Make yourself proud, don't let yourself down on this test. STUDY, STUDY, STUDY = Do practice problems!

1.) Complete the review "packet" with some multiple choice and open ended provided in class!

• Probability Review Multiple Choice (Click Me!)

• Skip questions 5 and 6. Those are terrible questions.

• Probability Review MC KEY (Click Me!)
• Probability Review Open Ended (Potato Chips)

• For #2 it should say "use your answer to part D above"

• Probability Review Open Ended KEY

2.) AP Classroom!

• I have assigned 2 multiple choice assignments and 1 open ended assignment in AP Classroom...
• These will not be graded as a quiz or classwork, instead, these are tools you can use to study if you like!
• For the multiple choice be sure to look at your results and look over the solutions to anything you got wrong!
• For the free response you can just do it on paper--here's the key:
• Probability (Unit 4) Free Response Progress Check KEY

The key to studying is to first do the questions; then, check your work. However, don't just mark the wrong stuff wrong--that doesn't help you learn. If you answered a question incorrectly it's important you go back and try to figure out the correct approach! That's how you learn stuff!

3.) What are some of the topics on tomorrow's test? 

• 8 MC
• 15 open ended (15 if I count each a,b,c as its own question)
• Some topics to review: (all of this is covered in the review packets linked above)
• "at least 1 problems" v. "exactly one" problems
• Look at our first (ch. 14) quiz--know everything on here
• Everything on all of your past quizzes--chapter 14 in class quiz, chapter 14/15 Thanksgiving break quiz, ch. 16 quiz
• *No interpret expected value until Friday
• Know when/how to work with Venn diagrams
• Be able to create a Venn diagram and to find the overlap (like the soccer/bball problem in our notes)
• Conditional probability
• With two way tables
• With Venn diagrams
• With tree diagrams
• Find probabilities with a normal model (normalcdf!)
• Calculate probabilities "without replacement"--write out lines, use words (back to basics!)
• Create and use tree diagrams!
• Calculate expected value and/or create a probability model
• Combine random variables--find the new mean and standard deviation
• "Variances always add"
• Look over the weekend HW--something like this on our test!
• Shifting/Rescaling random variables--look over our stamp problem based on these ideas; the first question is a MC with a table listing "# of cubic yards"
• If you do all of the review stuff linked above (under #1) you will cover all of these topics!

4.) I will accept any missing homework assignments tomorrow for full credit.

Feel free to send Remind messages with questions; see you all tomorrow! Come ready to earn an A!

Vocab Test: if you're going to be here Friday I wouldn't worry about this, but if you have to do the test tomorrow because you'll be out, here's what you need to know:

• 2-3 additional multiple choice, 1 open ended
• Open Ended = interpret expected value
• MC = more probability
• Binompdf and binomcdf

One last probability HW + Study

1.) You have one last homework assignment for our probability unit--the "Geometric and Binomial Probability" assignment provided in class (or linked below).

• This is due Wednesday!
• Geometric and Binomial Probability HW (Click Me!)
• After today's notes you should be able to complete the following:
• *Note: if we have a snow day tomorrow I will only be checking for these problems on Wednesday
• a, b, c, d, e, f, g, h, i, j, k, 
• I haven't taught you how to do c or d, but you don't need me to! Use some proportions and do some cross multiplying to solve; you got this
• For j, "found among the first 3 people surveyed," is another way of saying "the first person who speaks a language other than English at home is the 1st person surveyed, or the 2nd person surveyed, or the 3rd person surveyed."
• Check your answers! (provided in parentheses)

2.) STUDY, STUDY, STUDY = Do practice problems!

• If we have a snow day tomorrow take advantage of some extra time to study!
• I will not be available after school on Wednesday or F period Wednesday to help (meetings, boo); I WILL be after school until 2:40 on Tuesday
• How can I study for the test!
• Our vocab test (Friday 12/20) will be based on reviewing notes/vocab, but our math test (Thursday 12/19) is all about doing practice, practice, practice....lots of problems

1. Complete the review "packet" with some multiple choice and open ended provided in class!

Weekend HW + Review for Test

Lots to read in this blog post:

1.) Weekend HW = more combining random variables practice!

• Weekend HW: 33, 37, 38 (Click Me!)
• These questions are linked below or are the sheet you took in class, but they're also just taken from our textbook: p. 383-384: 33, 38, 38
• For 33abc look at today's example from our "stereo slide," question 2!
• For 33de it's more like question 1 on our "stereo slide" notes
• 37 and 38 are very similar--find the mean and standard deviation for the total team time/total setup time, then use these values to calculate a probability!
• You have to write a sentence for b!
• Always check your answers! Here's a link to the key:
• You'll definitely have to do something like this on our test, so be sure to understand this stuff!
• 33, 37, 38 Answer KEY with work! (Click me)

2.) START STUDYING for your test!

• I will not be available after school on Wednesday or F period Wednesday to help (meetings, boo), so it's a good idea to start studying now! I WILL be after school Monday if you have questions, or if you want to come to study!
• After school Monday = study session! Come work with classmates on the review practice!
• How can I study for the test!
• Our vocab test (Friday 12/20) will be based on reviewing notes/vocab, but our math test (Thursday 12/19) is all about doing practice, practice, practice....lots of problems

1. Complete the review "packet" with some multiple choice and open ended provided in class!

It's not break yet! Work hard this weekend to prepare for our test--the last tests of the second quarter!

Thursday HW!

HW, HW, HW....practice is the key to probability! Stay engaged, stay motivated, and work hard--we have to be ready for this test next week!

Thursday's HW: 2 things....

1.) Please complete question 1 on the last slide in our notes (or below)--do this question near the slide in your notebook.

• For this question we're looking at packing two items only, so we only need the "packing" numbers--we won't use the boxing numbers for #1
• Step 1: Find the mean and standard deviation for packing two systems! Look at today's notes about dogs and cats
• Answers: 
• E(packing time for two systems) = 18 min
• St. Dev(packing time for two systems) = 2.12 min
• Step 2: Use your mean and standard deviation for two systems, and the fact that packing times are Normally distributed, to find the probability it takes over 20 minutes to pack 2 systems!
• Normalcdf!
• Be sure to show a shaded model and normalcdf with each value labeled

2.) Please complete the following in your textbook:

• Page 383: 25, 27ab, 31bc
• 25 uses some of the ideas of rescaling with combining random variables...
• For example, look at #26:
• 26a.) 2Y + 20
• E(2Y + 20) = 2(12) + 20 = 44
• St. Dev(2Y + 20) = 2(3) = 6 (we don't add 20 because shifting doesn't affect st. dev)
• 26c.) 0.25X + Y
• E(0.25X +Y) = 0.25(80) + 12 = 32
• St. Dev(0.25X + Y)
• First, find the st. dev for 0.25X = 0.25(80) = 20
• From here, we can't add standard deviations...variances always add, so we do 20^2 + 3^2 = 409. 409 is the variance, so st. dev. = sqrt(409) = 20.223
• 27ab and 31bc are more like the dogs/cats examples from our notes today

If you were out today here are the notes from our slides about cats and dogs:

And here is the slide for the homework question:

Lastly, many people have been asking if we'll have work over break....kinda/maybe...

• Our next unit when we come back from break is about how to collect data; you will have to read chapter 13 (experiments and observational studies), take notes/answer questions based on your reading, and then complete a multiple choice packet--this will all be on your own
• This assignment will be due the Tuesday after 3 Kings Day (1/7)
• I will post the assignment on the blog, so if you want to do it over break, you can (and then not stress that 3 day weekend)
• Or, if you want to just enjoy the break, you can save all this for the 3 day weekend...your call.
