The table below summarizes data from a survey of a sample of women. Using a 0.01 significance level, and assuming that the sample sizes of 900 men and 400 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? a. Compute the test statistic. (Round to three decimal places as needed.) b. Find the critical value(s). (Round to three decimal places as needed. Use a comma to separate answers as needed.)
