Here's the chapter 11 vocab list:
- Random (Outcome)
- Pseudorandom Number
- Response Variable
- Outcome
- Component
- Trial
- Sample Survey
- Simulation
- Experiment (know what it is and that it's the only way to establish cause-and-effect)
- Observational Study
- Given a context identify the component, outcome, and response variable
And if you want some extra practice to get ready for the "design a simulation quiz" check these out:
- Page 267: 11
- Try the problem on the back of today's stamp....
- Look in your Barron's book! Simulations fall under the "Probability" heading! Use the table of contents to find the simulation section!
- In the 8th edition this starts on page 213!
- Here's the answer to the problem on the back of the stamp so you can check yours:
- Generate 2 digit numbers for 00-99.
- For the first test, let 00-33 represent passing and 34-99 represent failing.
- For subsequent tests (every test after the first), let 00-71 represent passing and let 72-99 represent failing.
- Generate a random number. If the student passes, the trial is over. If the student fails, generate a second random number and determine if the student passed/failed on the second test. Never generate more than 2 random numbers.
- Record whether or not the student has their license after 2 (or 1) attempts.
- Repeat.
- For your conclusion you will find a probability/percentage--find the percent of times a student had their license after 2 (or 1) attempts. (# of students who have their license within 2 attempts out of the total number of trials).
You'll have about 20ish minutes for your 2 quizzes (maybe 25), and then we'll start to discuss sample surveys! See you there!
