Consider the hypothesis test given by H_0:p = 0.5 H_1: p > 0.5 In a random sample of 625 subjects, the sample proportion is found to be p = 0.55. Determine the test statistic. Show all work; writing the correct test statistic, without supporting work, will receive no credit. Determine the P-value for this test. Show all work; writing the correct P-value, without supporting work, will receive no credit. Is there sufficient evidence to justify the rejection of H_0 at the alpha = 0.01 level? Explain.
