A filling procedure is supposed to fill jars with 16 ounces of grape jelly. Specifications state that each jar should contain between 15.95 and 16.05 ounces. A jar is selected from procedure every half hour till a sample of 100 jars is obtained. When fills of the jars are measured, it is found that = 16.02 and s = .02454. Using and s as point estimates of and, µ, estimate the probability that the randomly selected jar will have a fill, x, that is out of specification. Assume that the process is in control and that the population of all jar fills is normally distributed.
