Use a x-test to test the claim o=0.47 at the a=0.10 significance level using sample statistics s² = 0.479 and n =21. Assume the population is normally distributed. Identify the null and alternative hypotheses. OA. Ho: o² ≤0.47 H₂:0² > 0.47 OC. Ho: o² 20.47 H₂:0² <0.47 Identify the standardized test statistic. (Round to two decimal places as needed.) Identify the critical value(s). (Round to two decimal places as needed. Use a comma to separate answers as needed.) Choose the correct conclusion below. OB. Ho: o² #0.47 H₂: o² = 0.47 OD. Ho: o² = 0.47 H₂:0² #0.47 O A. Reject Ho. There is not enough evidence at the 10% level of significance to reject the claim. OB. Reject Ho. There is enough evidence at the 10% level of significance to reject the claim. O C. Fail to reject Ho. There is not enough evidence at the 10% level of significance to reject the claim. O D. Fail to reject Ho. There is enough evidence at the 10% level of significance to reject the claim. 19
