A random sample of 12 radon detectors of a certain type was selected, and each was exposed to 100 pCi/l of radon. The resulting readings have a mean of 102.72 pCi/l and a standard deviation of 6.11 pCi/l. Assume normal population, test at a = 0.01 that mean reading of all detectors of this type under these conditions is higher than 100 pCi/l using classical approach. Please show all 4 steps and interpret your conclusion.
