Consider the hypothesis test given by H0 p=0.5 H1>0.5
In a random sample of 625 subjects, the sample proportion is found to be pˆ= .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 H0 at the 0.01 level?
