To test Ho: H = 107 versus H1: µ# 107 a simple random sample of size n = 35 is obtained. Complete parts a through e below. Click here to view the t-Distribution Area in Right Tail. .... (a) Does the population have to be normally distributed to test this hypothesis? Why? A. No, because n2 30. B. Yes, because the sample is random. C. Yes, because n2 30. D. No, because the test is two-tailed. (b) If x = 103.8 and s = 5.9, compute the test statistic. The test statistic is to = |. (Round to two decimal places as needed.)
