The table below summarizes data from a survey of a sample of women. Using a
0.050.05
significance level, and assuming that the sample sizes of
800800
men and
300300
women are predetermined, test the claim that the proportions of agree/disagree responses are the same for subjects interviewed by men and the subjects interviewed by women. Does it appear that the gender of the interviewer affected the responses of women?
