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 800 men and 300 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? Compute the test statistic. (Round to 3 decimal places) Find the critical value(s). (Round to 3 decimal places. Use a comma to separate answers as needed.) What is the conclusion based on the hypothesis test? ▼ (Fail to reject/Reject) H0.There ▼ (is not/ is) sufficient evidence to warrant rejection of the claim that the proportions of agree/disagree responses are the same for subjects interviewed by men and the subjects interviewed by women. It ▼ (does not appear/ appears) that the gender of the interviewer affected the responses of women.

Kenneth, a competitor in cup stacking, claims that his average stacking time is 8.2 seconds. During a practice session, Kenneth has a sample stacking time mean of 7.8 seconds based on 11 trials. At the 4% significance level, does the data provide sufficient evidence to conclude that Kenneth's mean stacking time is less than 8.2 seconds?
