A quality engineer knows from past data that in a shipment lot, the number of wire cables that have tensile strengths below the lower specification limit follows a Poisson distribution with a mean of 50. For a sample of 45 shipment lots, what is the probability that the sample mean for the number of wire cables with tensile strengths below the lower specification limit exceeds 53?
