Test the claim that the proportion of men who own cats is smaller than the proportion of women who own cats at the .10 significance level. The null and alternative hypothesis would be: = HF Ho:PM = PF Ho:HM = HF Ho:pM = PF = µF Ho:PM = PF Ho:UM Ho: HM H1:HM < HF H:PM > PF H1:PM#HF H1:pM < PF H1:HM > µF H1:PM PF %3D %3D The test is: right-tailed two-tailed left-tailed Based on a sample of 20 men, 25% owned cats Based on a sample of 40 women, 45% owned cats The test statistic is: (to 2 decimals) The critical value is: (to 2 decimals) Based on this we: O Reject the null hypothesis O Fail to reject the null hypothesis > Next Question

Test the claim that the mean GPA of night students is significantly different than the mean GPA of day students at the 0.02 significance level. (a)  The null and alternative hypothesis would be:  H0:πN=πD H1:πN<πD   H0:μN=μD H1:μN<μD   H0:μN=μD H1:μN>μD   H0:πN=πD H1:πN>πD   H0:πN=πD H1:πN≠πD   H0:μN=μD H1:μN≠μD     (b)  The test is:  right-tailed left-tailed two-tailed   The sample consisted of 45 night students, with a sample mean GPA of 3.02 and a standard deviation of 0.08, and 45 day students, with a sample mean GPA of 3.01 and a standard deviation of 0.03. (c)  The t-score is: (Round to 2 decimal places.) (d)  The p-value is: (Round to 4 decimal places.) (e)  Based on this we conclude: null is plausible strong support for the alternative
