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= 23.2 and the sample standard deviation is found to be s= 6.3. Determine if the population mean is c 26 at the a = 0.01 level of significance. Complete parts (a) through (d) below. (a) Determine the null and alternative hypotheses. Ho: V 26 H,: V26 (b) Calculate the P-value. P-value =O (Round three decimal places as needed.) (c) State the conclusion for the test. O A. Reject H, because the P.value is greater than the a = 0.01 level of significance. O B. Reject H, because the P-value is less than the a = 0.01 level of significance. OC. Do not reject Ho because the P-value is less than the a = 0.01 level of significance. O D. Do not reject Ho because the P-value is greater than the a = 0.01 level of significance.

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 = 23.2 and the sample standard deviation is found to be s = 6.3. Determine if the population mean is different from 26 at the a = 0.01 level of significance. Complete parts (a) through (d) below. ..... (a) Determine the null and alternative hypotheses. Ho: 26 H1: 26 (b) Calculate the P-value. P-value = (Round to three decimal places as needed.) (c) State the conclusion for the test. A. Reject Ho because the P-value is greater than the a = 0.01 level of significance. B. Reject Ho because the P-value is less than the a = 0.01 level of significance. O C. Do not reject H, because the P-value is less than the a = 0.01 level of significance. D. Do not reject H, because the P-value is greater than the a = 0.01 level of significance.
