Bobbie Ruth has kept some records on demand. A weekly demand history for each of the three products follows. Demand is in items, e.g., number of stools, rockers, or swings. These numbers include items sold plus orders not filled because of insufficient supply. Week 1 is the first week of January 1995, and week 117 is the fourth week of March 1997.

How confident are you of your results? Suppose the actual demands for products in the next four weeks are the following: Swings Stools 100 109 Week Rockers 117 344 24 352 368 118 146 119 90 279 120 106 361 64 Does this change your recommendation for weeks 121-124? Explain. PIC•C
