Suppose we test H0: $\pi$1 = $\pi$2 at the 0.05 level of significance. If the z-test statistic is -1.07, what is our decision?
A) Reject the null hypothesis.
B) Do not reject the null hypothesis.
C) Take a larger sample.
D) Reserve judgment.

Since the z-test statistic (-1.07) does not fall in the rejection region for a two-tailed test at 0.05 level of significance, we fail to reject the null hypothesis. Therefore, the answer is do not reject the null hypothesis.

Suppose We Test H0 π\piπ 1 = π\piπ 2 at the 0

Suppose We Test H0 $\pi$ 1 = $\pi$ 2 at the 0
