Many doctors are concerned about changes in the skin thickness due to scar tissue build up. Suppose the historical mean thickness of the skin on an average male, is 3.32 mm. A recent random sample (n=28) of the skin on an average male was obtained. The sample mean skin thickness is 4.036 mm, sample standard deviation s=2.8 mm. Assume the underlying distribution is normal. How would I conduct a hypothesis test to determine whether there is any change in the mean skin thickness. Use α=0.01. I'd like to solve by both P-value method and reject region method. Keep all values in mm.
