Suppose that the demands for a company's product in weeks 1, 2,and 3 are each normally distributed. The means are 50, 45, and 75.The standard deviations are 10, 5, and 15. Assume that these threedemands are probabilistically independent.
Suppose that the company currently has 180 units in stock, andit will not be receiving any more shipments from its supplier forat least three weeks. What is the probability that stock will runout during this three-week period? Round your answer to threedecimal places, if necessary.
How many units should the company currently have in stock sothat it can be 98% certain of not running out during thisthree-week period? Again, assume that it won't receive any moreshipments during this period. Round your answer up to the nearestwhole number, if necessary.
