Q1 6 marks As mentioned in the chapter, opinion-polling organizations contact their respondents by sampling random telephone numbers. Although interviewers can reach about 62% of U.S. households, the percentage of those contacted who agree to cooperate with the survey fell from 43% in 1997 to 14% in 2012. (Source: Pew Research Center for the People and the Press). Each house-hold, of course, is independent of the others. Using the cooperation rate from 2012, a) what is the probability that the next household on the list will be contacted but will refuse to cooperate? b) what is the probability of failing to contact a house-hold or of contacting the household but not getting them to agree to the interview? c) show another way to calculate the probability in b). Q2 6 marks Employment data at a large company reveal that 72% of the workers are married, that 44% are college graduates, and that half of the college grades are married.
