According to Pew Research, the contact rate (probability of contacting a selected household) in 1997 was 69% and in 2003 was 76%. However, the cooperation rate (proability of someone at the contacted household agreeing to be interviewed) was 58% in 1997 and dropped to 38% in 2003.
a). What is the probablity (in 2003) of obtaining an interview with the next household on the sample list?
Is the answer 1-(.76)(.38)
b). Was it more likely to obtain an interview from a randomly selected household in 1997 or in 2003?
Is the answer to compare 1-(.76)(.38) and 1-(.69)(.58).
a) I belive your answer is the probability of NOT getting an interview. I think the answer is (.76)(.38)
b) adjust accordingly from a)
