Friday HW/Vocab Quiz Monday!

This weekend you have two responsibilities:

1.) Please complete the AP Free Response problem provided in class (or below)! Add part c!

• I accidentally cut off part c! After you design a simulation (procedure) and then simulate, I need you to interpret your results:
• Part c: "Based on your simulation, how many prizes do you expect to award each week?

Here's a link to the AP scoring rubric (2001) so you can check your homework answer! Scroll down to question 3.

2.) CHAPTER 11 VOCAB QUIZ TO START CLASS ON MONDAY! Here's the list:

• Random (Outcome) (in your notes or ch. 11 glossary)
• Pseudorandom Number (in your notes or ch. 11 glossary)
• Component (in your notes or ch. 11 glossary)
• Outcome (in your notes or ch. 11 glossary)
• Trial (in your notes or ch. 11 glossary)
• Response Variable (in your notes or ch. 11 glossary)
• Simulation (in your notes or ch. 11 glossary)
• Experiment (in your notes)
• Sample Survey (in your notes)
• Observational Study (in your notes)
• Then, there are three more questions--you are given a context and asked to identify the:
• Component (remember, this is the "most basic outcome." Think--when we look at a random number, what are we using it to represent happening? For our in class examples, the component was "having a child," or "picking a student for the dorm."
• Outcome: think about what you might label each number as--for our in class examples, we had two outcomes--either "girl or boy" for our first example, or "varsity or not varsity" for our dorm example
• Response Variable: remember, this is what you are measuring; for our in class examples, the response variable was "number of children in the family," or "whether or not all 3 students selected were on the varsity team"

And here is the procedure for the back of the paper we did today: You are about to take the road test for your driver's license. You hear that only 34% of candidates pass the test for the first time. This percentage rises to 72% on subsequent retests. Estimate the percentage of those tested who still do not have a driver's license after two attempts.

1. Generate two digit random numbers from 00 to 99.
2. For the first test, let 00-33 represent passing and 34-99 represent failing.
3. For any tests after the first test, let 00-71 represent passing and 72-99 failing.
4. Generate a random number; if the student passes, the trial is ended. If the student fails, generate one more (a second) random number. (Do not generate more than 2 numbers).
5. Record whether or not the student passes within two tries.
6. Repeat.
7. Find the % of times that a person did not have their license within two attempts.
