Let ny = 100, X1 = 70, n2 = 100, and X2 = 90. Complete parts (a) and (b) below. . a. At the 0.05 level of significance, is there evidence of a significant difference between the two population proportions? Determine the null and alternative hypotheses. Choose the correct answer below. O A. Ho ty the Hp : ty < 12 OB. Ho ty = 12 Hp : R1 ER2 Oc. Ho ty z 2 Hp : t1 = 12 OD. Ho. ST2 Hp : ty > 2 Calculate the test statistic, ZSTAT, based on the difference P1 - P2 The test statistic, ZSTAT, is (Type an integer or a decimal. Round to two decimal places as needed.) Calculate the p-value. The p-value is (Type an integer or a decimal. Round to three decimal places as needed.) Determine a conclusion. Choose the correct answer below. the null hypothesis. There is evidence to support the claim that there is a significant difference between the two population proportions. b. Construct a 95% confidence interval estimate of the difference between the two population proportions. 054-1250 (Type integers or decimals. Round to four decimal places as needed.)
