Test the claim that the proportion of men who own cats is smaller than the proportion of women who own cats at the .025 significance level. The null and alternative hypothesis would be: Ho:PM = pF Ho:HM = HF Ho: HM = uF Ho:PM = pp Ho:4M = uF Ho:PM = pp H: PM > PF H:M # HF H:PM < HF H1:PM PF H1:HM > HF H:PM < PF The test is: two-tailed right-tailed left-tailed o Based on a sample of 40 men, 25% owned cats Based on a sample of 60 women, 45% owned cats va (to 2 decimals) The test statistic is: -2.03 The critical value is: -0.67 x (to 2 decimals)
