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 = 27.9 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 Hy: H # 26 (b) Calculate the P-value. P-value= (Round to three decimal places as needed.)
