    (See attached file for full problem description)

    The Westar hotel, a 250-room business hotel located in a resort area of the Colorado Rockies, has two lounges on its premises: the Pour Nous Lounge, a pub-style lounge that seats about 50, and Gaiete, a 200-seat nightclub.

    Jane Bartley is a staff analyst for Westar's corporate parent, charged (among other things) with predicting and analyzing beverage sales (liquor, beer, and wine, primarily) for the chain's business hotels. In fact, her deadline for producing some sort of forecast for Westar beverage sales was the end of the week. After years in the business, Jane had seen a lot of approaches to forecasting beverage sales, but none that struck her as particularly helpful. Most of them used only room occupancy as a basis for forecasting.

    What factors appear to influence beverage sales at the Westar?

    Should Westar consider re-hiring the piano player for the Pour Nous Lounge?

    How about happy hour food?

    Can you suggest a new forecasting method for Jane to try out?
