To test Ho: μ= 40 versus H₁ μ#40, a simple random sample of size n = 35 is obtained. Complete parts (a) through (f) below. Click the icon to view the table of critical t-values. (a) Does the population have to be normally distributed to test this hypothesis by using t-distribution methods? Why? OA. No-there are no constraints in order to perform a hypothesis test. OB. Yes-the population must be normally distributed in all cases in order to perform a hypothesis test. OC. No-since the sample size is at least 30, the underlying population does not need to be normally distributed. COD. Yes since the sample size is at not least 50, the underlying population does not need to be normally distributed. (b) If x= 43.9 and s= 9.1, compute the test statistic. to = (Round to two decimal places as needed.). (c) Draw a t-distribution with the area that represents the P-value shaded. Choose the correct graph below. O A. OB. O C. O Q TILF-D .. A Q possible O D.
