115. The weekly demand X for a slow-moving item has been found to be approximated well by a geometric distribution on the range {0, 1, 2, ... ) with mean weekly demand of 2.5 items. Generate 10 values of X demand per week, using random numbers from Table A.1. (Hint: For a geometric distribution on the range {9,9+1,... } with parameter p, the mean is 1/p +9 - 1.] 16. In Exercise 15, suppose that the demand has been found to have a Poisson distribution with mean 2.5 items per week. Generate 10 values of X demand per week, using random numbers from Table A.1. Discuss the differences between the geometric and the Poisson distributions.
