In 1987, an environmental action group reported a 65 % response to a questionnaire sent to all of its members. The subject of the questionnaire was ocean dumpin. On the basis of these results, the group expects a 65% to 75% response rate to its upcoming questionnaire on air pollution.
The environmental group's expectation is based on which of the following assumption?
A. The group's membership has not declined by more than 5% since 1987
B. The same number of surveys will be distributed as were distributed in 1987
C. People who are concerned about ocean dumping are even more concerned about air pollution
D. The response rate of one questionaire can be presented from that of another
E. The total amount of air pollution today is the same of it was in 1987.
The ans. is D, while I chose C.
Can not undertand the logic. SOS!!!
