⚫ Let p be the proportion of slips of paper that say "I have used illegal drugs". p is chosen by the researcher in advance. Each participant chooses a random slip of paper from the hat and answers "yes" or "no" to whether the statement on that slip is true. The slip is then returned to the hat. The researcher doesn't know which type of slip the participant had. • Let y be the probability that a participant will say "yes", ⚫ and d be the probability that a participant has used illegal drugs. 1. Find y in terms of d and p. 2. Given that the researcher is interested in the true proportion of people using illegal drugs, d, what would be the worst possible choice of p that the researcher could make in designing the survey? Explain. Now consider the following alternative system. Suppose that proportion p of the slips of paper say "I have used illegal drugs", but that now the remaining (1 - p) say "I was born in winter" rather than "I have not used illegal drugs". Assume that 1/4 of people are born in winter, and that a person's season of birth is independent of whether they have used illegal drugs. 3. Find d, in terms of y and p. 4. A randomized response survey like in part (3.) is conducted with 100 participants and p = ½. Each participant draws a slip of paper from a box (with replacement) and answers the question on the paper truthfully. At the end of the survey, the responses are counted and there are 20 "yes" responses and 80 "no" responses.

Page 5 of 6 Date: Name: YouruicKOl Mr. Banks is worried that he was overcharged by the automotive detailing shop when they cleaned his Mustang. He dropped his car off at 9: 00 am and picked it up at 11:00 am. The shop charges $35 per hour for labor together with a one-time $20 supplies fee. 7. Use the verbal model to help you write an equation that models total cost of having a car detailed. a. Cost Number Total One-Time of per Hour/ Supply Fee Cost Hours b. What are the independent and dependent variables? Is this equation in Standard form or Slope-Intercept form? Explain how you can tell. с. If the bill came to $125 for how many hours did Mr. Banks pay? (Use your equation to answer this question.) d. Should Mr. Banks speak to the manager? e.
