Use a x²-test to test the claim o<39 at the x = 0.05 significance level using sample statistics s= 34.7 and n = 21. Assume the population is normally distributed. O A. Ho: σ<39 H₂: 0239 O C. Ho: 0≤39 H₂: o> 39 Identify the test statistic. (Round to three decimal places as needed.) Identify the critical value(s). C ⒸB. Ho: 0239 H₂:σ<39 O D. Ho: o>39 H₂:σ≤39 (Round to three decimal places as needed. Use a comma to separate answers as needed.) Choose the correct conclusion below. O A. Fail to reject Ho. There is enough evidence at the 5% level of significance to support the claim. OB. Reject Ho. There is not enough evidence at the 5% level of significance to support the claim. O C. Fail to reject Ho. There is not enough evidence at the 5% level of significance to support the claim. O D. Reject Ho. There is enough evidence at the 5% level of significance to support the claim.
