(3 points) A random sample of 120 observations is selected from a binomial population with unknown probability of success p. The computed value of p is 0.76. (1) Test Ho : p = 0.5 against Ha : p > 0.5. Use a = 0.01. test statistic Z = critical z score The final conclusion is A. There is not sufficient evidence to reject the null hypothesis that p = 0.5. `B. We can reject the null hypothesis that p = 0.5 and accept that p > 0.5. 2) Test Ho : p = 0.65 against H. : p
