No explanations needed, only correct solution

Use a y2-test to test the claim o2 = 0.57 at the a = 0.05 significance level using sample statistics s" = 0.525 and n = 18. Assume the population is normally distributed. Identify the null and alternative hypotheses. O A. Ho: 02 #0.57 B. Ho: 02 = 0.57 Ha: 02 = 0.57 Ha: 02 #0.57 O C. Ho: 02 20.57 O D. Ho: 02 50.57 H : 62 0.57 Identify the test statistic. (Round to two decimal places as needed.)Test the claim about the population variance of at the level of significance a. Assume the population is normally distributed. Claim: 62 s 15.9; a = 0.05 Sample statistics: s = 29.45, n = 41 Write the null and alternative hypotheses. Ho: 62 Ha: 62 =
