Test the claim about the population variance of at the level of significance a. Assume the population is normally distributed. Claim: 62 18.3, a = 0.05 Sample statistics: s2=27.38, n =31 Write the null and alternative hypotheses H: Ha Find the critical value(s) and determine the rejection region. Select the correct and below and fill in the corresponding answer box(es) to complete your choice. (Round to three decimal places as needed.) OA. > OD. X2 > Calculate the test statistic. x2 =(Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis and interpret the decision in the context of the claim. Ho- There enough evidence at the 5% level of significance to the claim
