Consider the hypothesis test given by
Ho: p=0.5
H1: p less than 0.5
In a random sample of 100 subjects, the sample proportion is found to be p = 45 .0ˆ?
(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 a =0.01 level? Explain
