Consider the test H: 66 versus H₂:>66 using a large sample of size n=415. Assume=24. Complete parts a through g a Describe the sampling distribution of X Choose the correct answer below. OA. The sampling distribution is approximately uniform. OB. The sampling distribution is approximately normal despite the sample size not being sufficiently large OC. Since the sample size is sufficiently large, the sampling distribution is approximately normal. OD. The sampling distribution is skewed to the right b. Find the value of the test statistic if x=68.5, 2= (Round to two decimal places as needed) a. Refer to part b. Find the p-value of the test. p-value= (Round to three decimal places as needed.) d. Find the rejection region of the test for @=0.05. Choose the correct answer below. OA 2-1.645 or 21.645 OC. z<1.06 OE. Z-1.06 orz> 1.96 e. Refer to parts and d. Use the p-value approach to make the appropriate conclusion. Choose the correct answer below. =0.05 level of significance to conclude that p=66. OA. Do not reject Hy. There is sufficient evidence at the OB. Do not reject Hy. There is insufficient evidence at the =0.05 level of significance to conclude that µ> 66. OC. Reject H₂. There is sufficient evidence at the a=0.05 level of significance to conclude that p=66. OD. Reject Hy. There is sufficient evidence at the a=0.05 level of significance to conclude that >66. 1. Repeat parte, but use the rejection region approach. Choose the correct answer below. OA Reject H₂. There is sufficient evidence at the a=0.05 level of significance to conclude that p=66. OB. Do not reject Hy. There is sufficient evidence at the =0.05 level of significance to conclude that p=66. OC. Do not reject Hy. There is insufficient evidence at the =0.05 level of significance to conclude that μ> 66. OD. Reject H₂. There is sufficient evidence at the a=0.05 level of significance to conclude that > 66. g. Do the conclusions in parts and fagran? Choose the correct answer below. OA. No, because the p-value approach rejects H, and the rejection region approach does not reject H₂. OB. Yes, because both conclusions reject H.. OC. No, because the p-value approach does not reject H, and the rejection region approach rejects H OD. Yes, because both conclusions do not reject H OB. 241.645 OD. z>1.96 OF 21.645
