2-11 Increase the sample size on the news vendor problem in Section 2.7.1 from 30 days to 150. As in the original problem, use the same realized demands in column E for all values of q. Don't forget to change the statistical-summary and histogram cells appropriately at the bottom of the columns, as well as the cells referred to in the various graphics. What is the effect on the results? Based on your results, about what sample size (in days) would be needed to bring the maximum half-width of all five confidence intervals down to under = $1.50? Don't actually carry this out, but just get an estimate; see Section 6.3. 2-11 Increase the sample size on the news vendor problem in Section 2.7.1 from 30 days to 150.
