HW + Bonus Stamps!

Tonight please... 

1.) Complete the rest of you "Probability: The Basics" packet (the one with the spinner on it)

• Probability Intro HW (Click Me!)

2.) USE A DIFFERENT COLOR PEN/PENCIL TO GRADE YOUR WORK! ALWAYS! (key is linked below)

• Probability Intro HW KEY! (Click Me)

**You will not earn full credit for your homework if you do not check your answers and grade yourself!**

Bonus Stamps (Due Monday): + 4 stamps

• Answer the question below (#7 from our slides about roulette) "the long way."
• You must show ALL work
• Your answer should match our answer from Thursday's class when we did this "the short way" 
• Question:
• Suppose we play roulette 4 times...
• What is the probability that the 4 spins are not all red?
• This means we could have 0 red, 1 red, 2 red, or 3 red (just not all 4 red)
• Your challenge:
• Calculate the probability of 0 red, exactly 1 red, exactly 2 red, 3 red
• Add these for the probability that our 4 spins are "not all red"
• Answer should = 0.94966

Tomorrow in class we'll get into some of the vocabulary and concepts you read about in the textbook....see you there!

Wednesday HW!

You must always check your answers/correct your homework to receive full credit. This is the policy for the remainder of the school year. If you do not do so, you will not be given full credit. 

Why? (is Carofano making me do this)

• Learning = making mistakes and correcting them
• Learning = using a given answer to work backwards and develop your understanding
• That's the whole point of our homework--to learn and practice for our quizzes tests!

Wednesday Homework:

1.) Please complete the following in your textbook:

• Page 340: 11, 13
• Page 342: 28abcd, 29abd 

2.) CHECK YOUR ANSWERS! Use a different color pen/pencil to grade yourself/make corrections. If you got something wrong, figure out why! That's how we get better at stuff!

• 11, 13, and 29 can be found in the back of the book.
• Here are the answers to 28:
• 28a.) lemon and lemon and lemon = (0.3)^3 = 0.027
• 28b.) no fruit and no fruit and no fruit = (0.5)^3 = 0.125
• 28c.) bell and bell and bell = (0.1)^3 = 0.001
• 28d.) no bell and no bell and no bell = (0.9)^3 = 0.729

Bonus Stamps (Due Friday): + 4 stamps

Tuesday = Actual Math Homework!

Yay for a new unit! Yay for math!

Tonight please... 

1.) Complete questions 1-10 and all of 12

• Probability Intro HW (Click Me!)

2.) USE A DIFFERENT COLOR PEN/PENCIL TO GRADE YOUR WORK! (key is linked below)

• Probability Intro HW KEY (1-10, 12)

**You will not earn full credit for your homework if you do not check your answers and grade yourself!**

Tomorrow in class we'll continue to focus on "the math," as we work through the rest of our slide examples. We'll also discuss any questions from the book work that was due today (p. 340: 9, 17, 23), and then we'll discuss independent and disjoint events if we have time.

Our goal will be to have a probability quiz on either Friday or Monday and to finish all of chapters 14/15 before Thanksgiving break, then ultimately test on probability right before winter break.

Spirit Week, Sub Work, Weekend

*The AP classroom MC deadline was extended to 7:00 am tomorrow for those of you who had "technical difficulties."

Everyone have fun tonight! Sleep a little!

Unfortunately I'm out tomorrow so I'm going to miss the fun--take some pictures for me! 

Here's the plan for tomorrow--Friday's sub work + weekend HW:

• Please complete the probability intro notes/practice packet! The more you get done in class, the less you have to do this weekend!
• Parts 1-3 are graded as classwork and will be collected on Tuesday
• Part 4 (reading questions = notes) and the textbook problems will be graded as a double homework on Tuesday
• Just read all of the directions!
• If you were out Friday, get this done! Here's the stuff (you can print this or write all answers on separate paper):
• Probability Intro Notes/Practice

When we get back to class Tuesday it's time for a new unit--probability! Be ready for lots of math problems on Tuesday. Bring your calculator.I can't wait!

Until then, have an awesome Pep-Rally-Day and long weekend. Rest up, have fun, and come back recharged and ready to ace another unit of AP Stat! 

TEST TOMORROW!

1.) Your AP Classroom assignment must be completed before Midnight!

• The multiple choice (18 questions) count as a QUIZ GRADE!
• The free response is just offered as a tool for you to use to study--this will not count as a grade!
• Just try the AP Classroom FR on separate paper and use the key below to check your work--or, at least read through this key (even if you didn't do them)!
• Unit 2 Progress Check: Free Response KEY! (Click Me)

2.) STUDY! Tomorrow = AP Free Response and Multiple Choice Test

• Here's how to study:
• 1.) Complete the AP Classroom assignment
• 2.) Review all of your writing interpretations--this test will have a good amount of writing, but it's all stuff we've seen...
• Describe an association (reference r if possible)
• Is a linear model appropriate?
• Interpret Slope
• Interpret Y Intercept
• Interpret R^2 (coefficient of determination)
• Interpret the meaning of a residual
• Of course do this all in context!
• 3.) More practice problems you can use to study: if you complete some/all of these on separate paper and turn them in tomorrow you will be given extra credit!
• Page 215: #9, 10
• Check answers in the back of the book for 9, you can send me a Remind message or show me your work in person next week for 10 to check
• Pages 245-253: (review of Part II/Unit II): 1, 3, 7ab, 11abcd, 15acd, 17, 27, 29abc, 39
• Here's a list of what you need to know for your test:
• *There is no create scatterplot/create residual plot/find equation on your graphing calculator stuff on your test tomorrow!
• Make predictions given an LSRL equation
• Calculate residuals given the LSRL and an actual value (or given a graph)
• Resid = actual - predicted
• Look at our rollercoaster stamp!
• Find an actual (y) value given a residual and the LSRL equation (or given a graph of residuals)
• Resid = actual - predicted
• Look at our rollercoaster stamp! 
• Interpret the meaning of a residual, in context
• More rollercoaster stamp! Also was in 47 in a past hw!
• Describe an association
• Context, Shape, direction, strength, reference r
• Find r given R^2
• Take square root of R^2, check scatterplot and/or slope to see if r is positive or negative
• Determine if a linear model is appropriate
• Scatterplot is roughly linear, residual plot has no pattern/random scatter, 2 quantitative variables--be sure to specify which graph you're talking about when you write this!
• Read a computer output 
• We have notes about this--# of passenger seats v. operating cost per hour
• Write the LSRL equation algebraically
• Notes about SAT scores on this! Remember, you're given the formulas...
• Interpret slope, in context
• Always...
• Interpret y-int, in context
• Always...
• Interpret R^2, in context
• Remember, % of changes in y that are explained by changes in x
• Also be sure to look at question 4 about size of homes and electricity useage from Monday's classwork (passed back today)--the answer was A!
• Predict using a re-expressed model with logs
• This is what we discussed today; it's on your test
• If you were out come prepared! No excuses!
• Also AP classroom MC #16 (I think it's #16)
• Understand how adding/removing a point influences slope, intercept, and correlation 
• This was the focus of Monday's classwork!
• We also have 3 slides in our notes
• Pay close attention to if we're adding/removing the points and if the correlation was negative or positive to start

After tomorrow's test it's on to probability--until then, STUDY! Start the 2nd quarter off strong!
