Complete parts(a) and(b) below.

Let n, = 80. X, = 60, n2 = 80, and X2 = 40. Complete parts (a) and (b) below. a. At the 0.10 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. OA. Ho: 1 # 142 OB. Ho: 1 5X2 H1: 1 = $2 H1 : 1 1 > 12 OC. Ho: #1 212 OD. Ho: $1 = #2 H1: *1 # # 2 Calculate the test statistic. ZSTAT, based on the difference p1 - Pz. 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 90% confidence interval estimate of the difference between the two population proportions. SX1 - 12 S (Type integers or decimals. Round to four decimal places as needed.)
