As international economic conditions worsen, ski resorts across Europe begin to notice a drop in the number of downhill racers who spend weekends and vacations on the slopes. A study covering 89 weeks compiled data for the number of guests at a ski lodge in Bern, Switzerland and the number of inches of snow each week. Treating inches of snow as a predictor of the number of “snow bunnies”

resulted in the following model:

a. Weather forecasts for this week predict 22 inches of fine powder.
At the 98% level of confidence, how many guests might the local resort prepare for?

b. What is the 95% interval estimate for the regression coefficient?
