Let ny = 80, X1 = 30, n2 = 80, and X2 = 40. 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. Ho i ty = 12 H₂ : Tq Ft2 O c. Hoity Sitz Hy : Ity > 2 OB. Ho: Iy2A2 Н.: п< 12 D. Hoity FT2 H₂ : 2q = 12 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. V 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. St1 - T₂ = , (Type integers or decimals. Round to four decimal places as needed.)
