An investigator is interested in the cigarette use of workers in factory. She asks all the workers who come into the site if they use cigarettes and determines that 20% of the subjects smoke. She then asks every third smoker who comes to the site how many cigarettes they smoke each day; she finds that the mean number of cigarettes smoked is 16. She plots the number of cigarettes smoked by each worker on a frequency distribution and finds that it is normally distributed. She also finds that the number of male smokers is equal to the number of female smokers. She already knows that half of her subjects are men, and half are women. A particular worker, Mr. X, smokes 24 cigarettes a day. What is the corresponding deviation score?
