The target thickness for silicon wafers used in a certain type
of integrated circuit is 245 𝜇m. A sample of 50 wafers is obtained
and the thickness of each one is determined, resulting in a sample
mean thickness of 246.18 𝜇m and a sample standard deviation of 3.60
𝜇m. Does this data suggest that true average wafer
thickness is something other than the target value? Perform a
hypothesis test, find the P-value, and state the
conclusion.
