Question

In a survey, the primary question of interest is, “Have you ever left the scene of an accident?” A randomized response design is used but instead of flipping a coin as in Exercise 3.22, the respondent is told to roll two dice. If the sum of the two dice is 2, 3, or 4, the respondent is to answer “yes.” If the sum is 5, 6, 7, 8, 9, or 10, the respondent is to answer according to the truth. If the sum is 11 or 12, the respondent is to answer “no.” Let p be the proportion in the population who has left the scene of an accident. The proportion responding “yes” is 0.4. What is an estimate of the proportion of people in the population who have left the scene of an accident?
