The null and alternate hypotheses are: H0: π1 ≤ π2 H1: π1 > π2 A sample of 100 observations from the first population indicat
ed that X1 is 70. A sample of 150 observations from the second population revealed X2 to be 90. Use the .05 significance level to test the hypothesis. a. State the decision rule. (Round your answer to 2 decimal places.) H0 is rejected if z > b. Compute the pooled proportion. (Round your answer to 2 decimal places.) Pooled proportion c. Compute the value of the test statistic. (Round your answer to 2 decimal places.) Value of the test statistic d. What is your decision regarding the null hypothesis? H0 is
