MyTech - Texas.. (3 points) A random sample of 90 observations is selected from a binomial population with unknown probability of success p. The computed value of p is 0.68. (1) Test Ho : p = 0.65 against Ha : p > 0.65. Use a = 0.01. test statistic z = critical z score The final conclusion is A. We can reject the null hypothesis that p = 0.65 and accept that p > 0.65. B. There is not sufficient evidence to reject the null hypothesis that p = 0.65. (2) Test Ho : p = 0.55 against Ha : p
