This Question: 1 pt 8 of 10 (8 complete) This QUIZ: 10 pts possible A simple random sample of size n= 15 is drawn from a population that is normally distributed. The sample mean is found to be x = 27.4 and the sample standard deviation is found to be s = 6.3. Determine if the population mean is different from 24 at the a=0.01 level of significance. Complete parts (a) through (d) below. (a) Determine the nul and alternative hypotheses. H: 24 (b) Calculate the p-value. P.value (Round to three decimal places as needed.) (c) State the conclusion for the test. O A. Do not reject Ho because the P-value is less than the c = 0.01 level of significance. OB. Do not reject Hy because the P-value is greater than the q=0.01 level of significance. OC. Reject Hy because the P-value is greater than the a=0.01 level of significance. O D. Reject He because the P-value is less than the c = 0.01 level of significance. (d) State the conclusion in context of the problem. There sufficient evidence at the a=0.01 level of significance to conclude that the population mean is different from 24 Click to select your answer(s).
