9.127 Standard error formulas Suppose you wanted to test H0: p = 0.50, but you had 0 successes in n trials. If you had found the test statistic by using the se = 2pn 11 - pn 2 >n designed for confidence intervals, show what happens to the test statistic. Explain why se0 = 2p011 - p02 >n is a more appropriate se for tests.
