he daily demand for printer paper at the School of Business is approximately normal with a mean of 15.2 boxes and a standard deviation of 1.6 per day. The Administrative Assistant reviews the inventory every 30 days, and the lead time is 5 days. The division set a policy of satisfying 96% of the demand for paper. If there are 125 boxes of printer paper in inventory at the beginning of this review period, how many boxes of printer paper should be ordered? What is the variance of demand during the review period plus the lead-time period? What is the standard deviation of demand during the review period plus the lead-time period? A. Variance = 76.80 Standard deviation = 8.76 B. Variance = 89.60 Standard deviation = 9.47 C. Variance = 9.47 Standard deviation = 89.60 D. Variance = 12.8 Standard deviation = 3.58
