Null is that the population mean is ten and thealternative hypothesis test is that is that the mean is lessthan ten. Given a sample of 50 and sample deviation of 2, use alpha=0.05, what is the critical value for Z? Compute the value ofthe test statistic.. What is your conclusion?
12 In line with Q11 above and assuming everything in thatquestion except that the alternative hypothesis is not equalto ten, sample mean is eleven, sample standard deviation is 2.5 andN=36. Answer step-by-step the same questions in Q11. (Answer step-by-step on a separate sheet)
