The null and alternative hypotheses are: Ho: P₁ P₂ 0 H₁: P₁-P₂0 A sample of 340 observations from the first population indicated that X₁ is 300. A sample of 320 observations from the second population revealed X2 to be 260. Use the 0.05 significance level to test the hypothesis. a. State the decision rule. (Negative answer should be indicated by a minus sign. Round the final answers to 2 decimal places.) The decision rule is to reject Ho if z[(Click to select) ( ]). b. Compute the pooled proportion.
