question 12

Multiple Choice

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.
