Question 1203047: One of the greatest problems in marketing research and other survey fields is
the problem of nonresponse to surveys. In home interviews the problem arises when
the respondent is not home at the time of the visit or, sometimes, simply refuses to
answer questions. A market researcher believes that a respondent will answer all questions with probability 0.94 if found at home. He further believes that the probability that a given person will be found at home is 0.65. Given this information, what percentage of the interviews will be successfully completed.
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! i believe it will be .65 * .94 = .611.
to understand how this works, assume 1,000 people are canvased.
65% of them are at home at the time of the canvasing = 650.
of those 650, 94% answer all questions = .94 * 650 = 611.
out of the 1000 people who were canvased, 611 answered all questions.
350 didn't answer because they weren't home when canvased.
39 didn't answer all questions even if they were home when canvassed.
that 611 who were home when canvased and answered all the questions.
