Question:

A random sample of 100 observations is selected from a binomial population with unknown probability of success, p. The computed value of p > is equal to .74.

a. Test H0: p = .65 against Ha: p > .65. Use a = .01.

b. Test H0: p = .65 against Ha: p > .65. Use a = .10.

c. Test H0: p = .90 against Ha: p ± .90. Use a = .05.

d. Form a 95% confidence interval for p.

e. Form a 99% confidence interval for p.
