Consider the hypothesis test given by H0 p05 H1 p 05 In a ra

Consider the hypothesis test given by H0: p=0.5 H1: p> 0.5; In a random sample of 400 subjects, the sample proportion is found to be p= 0.55 (a) Determine the test statistic. Show all work; writing the correct test statistic, without supporting work, will receive no credit. (b) Determine the P-value for this test. Show all work; writing the correct P-value, without supporting work, will receive no credit. (c) Is there sufficient evidence to justify the rejection of Ho at the = 0.01 level? Explain.
