In Large Sample Cases, Using a Significance Level of 5 $\pi$

In large sample cases, using a significance level of 5% in a one-tailed test in which the null hypothesis is $\pi$ ₁ < $\pi$ ₂, the decision rule is:

A) Reject the null hypothesis if $\pi$ ₁ - $\pi$ ₂ is greater than 0.
B) Reject the null hypothesis if the test statistic, z_stat, is either greater than −1.65 or less than +1.65.
C) Reject the null hypothesis if the p-value for the sample mean difference is less than .05.
D) Reject the null hypothesis if the difference in sample proportions is greater than 0.
