Let ny = 80, X1 = 30, n2 = 80, and X2 = 40. 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. Hot = 12 Hq : Tq #12 0C. Ho *T2 Hq : #1 = 72 ов. Но п1212 Hp : Tq <T2 OD. Ho:1 ST2 Hq : Tg > T2 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. $17-12-0 (Type integers or decimals. Round to four decimal places as needed.)
