The heat evolved in calories per gram of a cement mixture is approximately normally distributed. The mean is thought to be 99.6 and the standard deviation is 5.8. We wish to test Upper H Subscript 0 Baseline colon mu equals 99.6 versus Upper H Subscript 1 Baseline colon mu not-equals 99.6 with a sample of n = 9 specimens.
Calculate the P-value if the observed statistic is
