A random sample of 100 observations is selected from a binomial population with unknown probability of success, p. The computed value of p̂ is equal to.74.
a. Test H0: p =.65 against Ha: p >.65. Use α =.01.
b. Test H0: p =.65 against Ha: p >.65. Use α =.10.
c. Test H0: p =.90 against Ha: p ≠.90. Use α =.05.
d. Form a 95% confidence interval for p.
e. Form a 99% confidence interval for p.
