Question

Greg Gouge, analyst for the Wisconsin Department of Taxation, is concerned about beer consumption in the state. (The state taxes beer so a drop in consumption will reduce tax revenues.) The dependent variable is the number of gallons of beer consumed per person in a given year. The independent variable is a trend variable coded as 1 in 1995. A regression reveals the following:
 = 22.9 + .297 X r2 = .75 Sy|x = 1.92 sb = .028
Interpret the slope, intercept, and coefficient of determination. Test the slope for significance. Predict beer consumption for 2015.
