Question: Here are two questions about p-values and one-sided versus two-sided tests:

1. Under what conditions would the p-value for a one-sided z-test be greater than .5?

2. When the data are consistent with the direction of the alternative hypothesis for a one-sided test, the p-value for the corresponding two-sided test is double what it would be for the one-sided test. Use this information to explain why it would be cheating to look at the data before deciding whether to do a one- or two-sided test.
