Based on a simple random sample of 100 observations from a population, it is found that p = 0.68. Use this sample and answer each of the following questions. (1) Test Ho p = 0.6 against H p > 0.6. Use a = 0.05. a. test statistic z = b. critical z score c. The final conclusion is OA. There is not sufficient evidence to reject the null hypothesis that p = 0.6. OB. We can reject the null hypothesis that p = 0.6 and support that p > 0.6. a. test statistic z = (2) Test Ho: p=0.6 against H p
