The null and alternate hypotheses are: He: T1 ≤ 1₂ H₂: T₂ > TT₂ A sample of 100 observations from the first population indicated that x₁ is 70. A sample of 150 observations from the second population revealed x₂ to be 90. Use the 0.05 significance level to test the hypothesis. a. State the decision rule. (Round your answer to 2 decimal places.) HO is rejected if z> b. Compute the pooled proportion. (Round your answer to 2 decimal places.) Pooled proportion
