Let n = 50, X1 = 30, n2 = 50, and X2 = 10. Complete parts (a) and (b) below. = a. At the 0.01 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. Hoity S2 H₂ : ty > H2 O C. Hoity = 12 H₂ : 0, #12 OB. Ho: Tq 12 Hy : ay = 12 OD. Ho: 172m2 H₂ : ty <h2 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 99% confidence interval estimate of the difference between the two population proportions. - sau as (Type integers or decimals. Round to four decimal places as needed.)
