NOTE: Need assistance w/ PART 3 ONLY.

This problem focuses on a very profitable product that our company sells - the Tiger ONE widget or T1 for short. You have been asked to provide input on the ordering policy currently being used for the Ti. 2000 Part I-Demand Sales and marketing tracks actual weekly sales but report these sales by rounding to the nearest 1,000 units sold. For modeling purposes, we are assuming that the errors associated with rounding are not large enough to be of concern. The table below displays the sales volume and the number of weeks in the past year that each volume was realized. You can assume that nothing extraordinary was done to influence these numbers (e.g., sales promotions) so variability is due to natural market fluctuations. Weekly Sales Volume No. of Weeks this Sales Volume Occurred in the Past Yr. Pr(D) 1000 0.1154 0.0769 3000 0.1346 4000 0.1538 5000 0.1731 6000 0.1154 7000 0.0769 8000 0.0192 9000 0.0577 10000 0.0769 1
