Question: A randomized response technique for drunk driving is implemented. Respondent’s choose one of two cards at random:

A. I may have driven drunk in the last year

B. I have not driven drunk in the past year

With the probability 0.56 pull the respondent chooses the first (1) card and with the probability 0.44 the respondent choose card two (2). Without knowing which card the respondent has the interviewer asks “if the statement on the card is true?” The number of respondents is 100. Of these, 45 answer Yes to the question and the rest answers No.

Estimate the proportion that has driven drunk during the last year.
