A simple random sample of size nequals15 is drawn from a population that is normally distributed. The sample mean is found to be x overbarequals23.5 and the sample standard deviation is found to be sequals6.3. Determine if the population mean is different from 25 at the alpha equals 0.01 level of significance. Complete parts ​(a) through ​(d) below. ​(a) Determine the null and alternative hypotheses. Upper H 0​: mu equals 25 Upper H 1​: mu not equals 25 ​(b) Calculate the​ P-value. ​P-valueequals nothing
