Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 5 % significance level:
a) Test H 0 : p = 0.5 vs H a : p > 0.5 using the sample results p ^ = 0.60 with n = 50
b) Test H0 : p=0.3 vs Ha : p<0.3 using the sample results p^=0.20 with n=198
c) Test H0 : p=0.75 vs Ha : p≠0.75 using the sample results p^=0.70 with n=124
