We made it through a full week! Only three more to go until the holiday break!

Here's some fun homework for you to consider....make sure you're using the appropriate names of the sampling methods and biases!

This weekend, please complete....

3, 11, 13, 23, 26

(And you know I'm going to check it...)

Thursday HW

Tonight, please complete the following problems:

Page 289: 1, 5, 17, 22

When's day homework

Tonight, please complete the following:

Page 289:

19, 21, 31
Enjoy!

And don't forget--simulations quiz tomorrow!

One more night of simulations...

Tonight, please work on the following:

Page 268: 24 (10 trials), 29 (5 trials), 33 (10 trials)

For each scenario, please...

1. Write a procedure
2. Conduct trials (use your graphing calculator)
3. Write a conclusion!

Enjoy!

We'll have our in class simulation quiz once I return your take home quizzes--I want you to have a chance to see what you did right/wrong to study!

Back to work...

Tonight, please complete the (other 2) simulations provided in class (on the powerpoint slide handout).

Tomorrow we'll see how our answers match up against the group's suggestions to check our homework!

Thanksgiving HW

So the Thanksgiving take home quiz is due Monday (and uploaded under our resources and assignments)...

Here's the writing template for some procedure help...
1. Generate ___ digit random integers from ____ to ____.
2. Let _____ represent _____.... (define what numbers represent which categories)
3. Generate random integers until (provide a stopping rule!)
4. Record.... (what data should I record from my simulation?)
5. Repeat. Conduct ____ trials

And here are some HINTS:

• If you use numbers 01-50 you will have to ignore any numbers over 50; therefore, I recommend you either use 0-9 or 00-99
• To do that, many of you like percentages...
• Well, 5 people out of 50 win $200 so that's 5/50 or 10%.
• 15 people out of 50, or 30% win $100....
• And so on....
• Now you have percentages which will make your breakdowns easier!
• Also, this contest is done without replacement. That means once you use a number, it's out (for instance, if you draw a "3", then you cannot have another person win with a "3")

Thanksgiving! (Already?!)

Tis the time to give thanks...and if you're in a lot of AP classes, probably do a lot of homework. I did my part and gave you all some multiple choice and a simulation to enjoy!

So, for break, please complete the take home quiz--the simulation regarding blood type, as well as the multiple choice. I've uploaded these under our classroom resources in case you lost them.

Other than that, enjoy your time off. Maybe some Black Friday shopping? I still need NBA2K13 for my Xbox...

See you all Monday! Come back well rested and ready for a simulations quiz the week of our return!

And as always, feel free to email with any questions. fred.carofano@gmail.com.

Monday HW

One more day of class and our week is done!

Tonight, please do your best to complete the chapter 11 quiz C worksheet provided in class--don't just say you couldn't figure it out! You only have a little homework, so give it your best effort!

Hint: Since we (again) have percentages, I'd recommend generating numbers (well, reading them from below) from 00 to 99.

Here are some generic steps you might use to write your procedure....

1. Generate ___ digit random integers from ____ to ____.

2. Let _____ represent _____....   (define what numbers represent which categories)

3. Generate random integers until (provide a stopping rule!)

4. Record.... (what data should I record from my simulation?)

5. Repeat. Conduct ____ trials.

Weekend Homework

This weekend please complete the chapter 11 reading questions provided in class!

Be ready for some notes and a new unit when we return! You'll have a take home simulation over Thanksgiving so we have to make sure we're on top of things!

Jamel--here are the questions since you probably lost yours.

Chapter 11 Reading Questions:1. What does it mean for something to be random? (statistically speaking)
2. What are pseudorandom numbers?
3. What is a simulation?
4. What is a component?
5. Define a trial.
6. Define response variable.
7. Describe the 7 steps for creating a simulation (outlined at the bottom of page 260).
8. Write the steps you will follow on your calculator to generate random integers (yellow box on page 263!)

Complete page 266: 1,3, 4 (questions listed below):
1. Is a coin flip random? Why or why not, in your opinion?
3. Many states run lotteries, giving away millions of dollars if you match a certain set of winning numbers. How are those numbers determined? Do you think this method guarantees randomness? Why or why not?
4. Many kinds of games people play rely on randomness. What are (at least) 3 different ways commonly used to achieve randomness? In other words, pretend you’re trying to choose who will drive to the movies amongst 5 friends. What are at least 3 different ways you can randomly choose a driver?

Vocab Test Tomorrow!

Study, study, study! (for your vocab test).

Remember, you get 2 extra points for the crossword puzzle (due tomorrow)!

Good luck!

**I added 3 words that are not on the vocab list...**

1. Residual Plot
2. Underestimate
3. Overestimate

Wednesday

Tonight, please complete the following in your textbook (regarding re-expression):

Page 238

1, 3, 7, 31 (#7 has a lot of words but it's only asking you to use a formula; don't get scared!)

Also, you have a 10-minute pop quiz tomorrow--interpret slope, intercept, coefficient of determination (R^2), and correlation (r). All of the numbers are provided, you'll only be writing. Make sure you know what you're doing so you have time to finish!

*Hint: the quiz is based on the same data as last night's homework--so you can practice these questions ahead of time!

And also, remember our vocab test is Friday. The list is uploaded under our classroom resources link.

Twosday

Tonight, please complete the regression problems provided in class. These explore some of what we've learned, as well as extrapolation, influence, and leverage. Enjoy!

Tomorrow we'll talk about any questions you might have and begin chapter 10.

Remember, your vocab test is Friday! I've uploaded the vocab list as well as tonight's homework.

Weekend HW! Yay!

This weekend please complete the following:

Page 215: 10, 11, 13, 15


Enjoy your three day weekend! (We pretty much don't go to school anymore...)

*Take Home Quiz Still Due Tomorrow*

Despite the snow day, your take home quiz is still due tomorrow. You're on your own--you have plenty of notes and I have confidence in you!

Do your best! Get off to a good start for the second quarter!

See you manana!

Wednesday HW

Please complete for Friday:

1.) Take home quiz! (please do a through h on separate paper)

2.) Test score analysis (a little old school Stat)

Both of these will be graded!

(Sorry Monique--I'm not going to post the weekend homework b/c I'm not exactly sure where we'll be on Friday!)

I'm so excited...I just can't hide it!

Ok, so I'm only done grading the multiple choice section (36 of the 51 points)....but I couldn't resist a little update. The following people got me super excited by earning a 36 out of 36 on the multiple choice:

Monique Atkinson
Ashley Clancy
Matt Whitesell
Cindy Tran

And the following ladies weren't slackers with a 35/36:

Christina Thomas
Micaela Levesque

I'm so proud of you all! Just wanted to give you some good news to help enjoy the day off.

Let's get that facebook group active again!

Don't worry--there were plenty of good grades and people to be proud of. I'll get back to you when I finish grading!

Don't forget your homework--the questions provided in class and uploaded under our resources (see post below). This will count as a double homework so don't forget!

It's the most wonderful time of the year....(for Stats...)

There will be lots of Statistics (and statistics) to pay attention to over the next couple days with Tuesday being election day! Keep your eyes and ears open for some interesting info! We'll be doing some of the math the pollsters use to determine sample sizes and margin of error later in the year!

As for homework, please complete the questions provided in class--these include what we began Friday, as well as some chapter 9 reading questions.

• There is no need to re-write answers from Friday's worksheet--just staple these together and finish the rest
• Use your textbook (chapter 9) to complete each of the reading questions.

This is our first homework grade for the second quarter--so it's going to count extra! Get started on the right foot!

On Wednesday we will continue to discuss outliers, influence, and leverage.

Enjoy your day off!

(If you lost the questions I've attached this under our Classroom Resources, below assignments--"Chapter 9 Intro Questions."

Weekend!

After a short week it's already Friday...your homework this weekend is to STUDY FOR THE TEST! Remember, the test includes 12 multiple choice and 1 free response question. You will have the entire period (and if you finish early I'll give you some homework to start...)

Also, STAMPS ARE DUE MONDAY. Here's the deal for stamps....

• They must be collected and stapled/paperclipped together.
• The total number of stamps must be clearly written on the front (or I'll just assume you only have 1....)
• Double check your count! If your count is off (at all) when I double check you will be given a "0." No lieing (or counting wrong!)
• Not sure if it counts? Anything that is literally a stamp counts...

And finally, the answers to the few practice questions for the test are below...

1. According to the this data, each year the predicted average life expectancy in the U.S. increases by approximately 0.2157 years.

2. According to the model, in the year "0" the predicted average life expectancy was -353.87 years. This is unrealistic--life expectancy cannot be negative, nor should we consider the U.S. in year "0."

3. This R^2 tells us that 95.39% of the changes in life expectancy are due to changes in the year. Other factors may include advancement in medicine/science or the economic status of the U.S.

4. r = sqroot(0.9539) = 0.977

5. Residual = actual - predicted = 77.9 - 79.0399 = -1.1399 (I got the predicted value by substituting 2007 in the Least Squares Regression Line equation)

Thursday...

We will have a test Monday on chapters 7 and 8. Sweeeeeeet.

Tonight, please complete the AP Stat Quiz: Linear Regression worksheet provided in class. Again, this is not a quiz, but a homework to prepare for our upcoming test.

See ya'll tomorrow before the weekend!
