The null and alternate hypotheses are: H0: π1 ≤ π2 H1: π1 > π2 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.
H0 is rejected if z > ?
