Thursday HW = Important Practice!

Tonight, please complete the following in your textbook:

Page 266-268: 13, 19, 23

• For each; 1.) Write a procedure 2.) Simulate using a random number table 3.) Interpret your results (answer the question!)
• Conduct 5 trials for each simulation (not 20).
• I'm checking!
• Here are some hw hints:
• For each problem, consider: do you have to ignore repeats? Can a student repeatedly get multiple choice questions correct? Can a student repeatedly fail a driving test? If we draw a customer's coupon to win a prize, would we (repeat) and draw that customer's number again?
• #13: Think: how many random numbers should you generate to represent the test? Also, consider what numbers should represent a question being "right" or "wrong."
• #19: This is a tough one. This will be a simulation with "extra steps," because the probability of passing the driving test changes! In this example, someone has a 34% chance of passing on their first attempt, but they then have a 72% chance of passing any test after that! You also have to keep in mind that if a student passes the first time they will not take the test again, they're done. But, if a student fails the first time, they have to continue to take the test with a 72% chance to pass.
• #23: For this problem, you will have multiple (more than 2) categories represented by random numbers, as there are 4 different prizes that may be given out. When should you generate random numbers until? (When will the store stop handing out coupons)?

Remember, each simulation is different; our notes attempt to outline a generic process for writing a procedure, but each individual context will be a little different--you have to THINK about each situation! It's essential you get practice!

Tomorrow we'll do some classwork; then, on Monday we'll have our chapter 11 vocab quiz. Then, we'll start our notes on chapter 12. 

On Tuesday we'll start class with a chapter 11 quiz (a simulation).Then, we'll continue our chapter 12 notes. 

Oh...does anyone want a free copy of NBA 2K15? I just got 2K16 so I don't need it anymore! It's for XBox One. If you want it, email me and I'll raffle it off amongst all the emails I get! carofano.fm@easthartford.org.
