Consider the hypothesis test given by
H0 : p = 0.5
H1 : p > 0.5
In a random sample of 225 subjects, the sample proportion is found to be 0.55.
(a) Determine the test statistic.
(b) Determine the P-value for this test.
(c) Is there sufficient evidence to justify the rejection of H0 at the significant level of 0.01?
