(a) Does the population have to be normally distributed to test this hypothesis by using t-distribution methods? Why? A. Yes-the population must be normally distributed in all cases in order to perform a hypothesis test. B. No-since the sample size is at least 30, the underlying population does not need to be normally distributed. C. No-there are no constraints in order to perform a hypothesis test. OD. Yes since the sample size is at not least 50, the underlying population does not need to be normally distribut (b) If x= 53.8 and s= 8.9, compute the test statistic. to = (Round to two decimal places as needed.)
