Question:

Suppose you are testing the hypothesis H0: π = 0.50 versus Ha: π > 0.50. You get a sample proportion of 0.54 and find that your p-value is 0.08. Now suppose you redid your study with each of the following changes. Will your new p-value be larger or smaller than the 0.08 your first obtained?
a. You increase the sample size and still find a sample proportion of 0.54.
b. Keeping the sample size the same, you take a new sample and fi nd a sample proportion of 0.55.
c. With your original sample, you decided to test a two sided alternative instead of Ha: π > 0.50.
