Question: In 9.10, calculate the p-value if the observed statistics is

The heat evolved in calories per gram of a cement mixture is approximately normally distributed. The mean is thought to be 100 and the standard deviation is 2. We wish to test \({{H}_{0}}:\mu =100\) versus \({{H}_{1}}:\mu \ne 100\) with a sample of n = 9 specimens.

(a) \(\bar{X}=98\)

(b) \(\bar{X}=101\)

(c) \(\bar{X}=102\)
