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 = 21.1 and the sample standard deviation is found to be s = 6.3. Determine if the population mean is different from 24 at the x = 0.01 level of significance. Complete parts (a) through (d) below. (a) Determine the null and alternative hypotheses. = 24 Hoi H H₁: H * 24 (b) Calculate the P-value. P-value = 0.096 (Round to three decimal places as needed.) (c) State the conclusion for the test. O A. Reject Ho because the P-value is less than the x = 0.01 level of significance. OB. Do not reject Ho because the P-value is less than the x = 0.01 level of significance. Do not reject Ho because the P-value is greater than the x = 0.01 level of significance. O D. Reject Ho because the P-value is greater than the x = 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.
