Suppose are running a study/poll about the accuracy rate for fingerprint identification. You randomly sample 138 people and find that 58 of them match the condition you are testing. Suppose you are have the following null and alternative hypotheses for a test you are running: Ho : p = 0.39 Ha: p > 0.39 (a) Calculate the sample test statistic: p = (b) Calculate the standardarized test statistic (the z-score). Z
