Survey Refusals. In Exercises 2732, refer to the following table summarizing results from a study of people who refused to answer survey questions (based on data from "I Hear You Knocking but You Can't Come In," by Fitzgerald and Fuller, Sociological Methods and Research, Vol. 11, No. 1). In each case, assume that one of the subjects is randomly selected. Age 50-59 60 and over 18-21 22-29 30-39 40-49 136 138 202 Responded 73 255 245 Refused 20 33 16 27 49 27. Survey Refusals What is the probability that the selected person refused to an- swer? Does that probability value suggest that refusals are a problem for pollsters? Why or why not?Explanation / Answer
27)probabilty that selected person refuse to answer =156/1205= 0.1295
as this probability is low on value, hence it does not seem to be a problem
28)total number of people who responded or is in 18-21 age bracket =1049+11=1060
hence probability =1060/1205=0.8797
29)probability that subject responds or is b/w age of 22 and 39 =1049+20+33=1102
hence probability =1102/1205=0.9145
