Question
To get answers to sensitive questions, we sometimes
use a method called the randomized response technique.
Suppose, for instance, that we want to determine what
percentage of the students at a large university smoke
marijuana. We construct 20 flash cards, write “I smoke
marijuana at least once a week” on 12 of the cards, where
12 is an arbitrary choice, and “I do not smoke marijuana
at least once a week” on the others. Then, we let each stu-
dent (in the sample interviewed) select one of the 20 cards
at random and respond “yes” or “no” without divulging
the question.
(a) Establish a relationship between P(Y), the probabil-
ity that a student will give a “yes” response, and P(M),
the probability that a student randomly selected at that
university smokes marijuana at least once a week.
(b) If 106 of 250 students answered “yes” under these
conditions, use the result of part (a) and 106
250 as an esti-
mate of P(Y) to estimate P(M).
