A random sample of 140 observations is selected from a binomial pulation with unknown probability of success p. The computed value of p is 0.74 Test Ho: p = 0.65 against Hap > 0.65. Use a = 0.01. st statistic z = tical z score e final conclusion is A. We can reject the null hypothesis that p = 0.65 and accept that p > 0.65.
