The analyst decides to consider the independent variables age, the mean age (in months) of small businesses in the metropolitan area; and BizAnalyzer, the mean BizAnalyzer score of small businesses in the metropolitan area. The dependent variable, revenue, is mean annual revenue. Using data collected from a sample of 25 metropolitan areas, the regression results are:

a. State the multiple regression equation.

b. Interpret the meaning of the slopes, b1 and b2, in this problem.

c. What conclusions can you reach concerning mean annual revenue?
