Question: If you are given that the dependent variable (y) is Annual Sales, and \[{{x}_{1}}\] is the number of jobs held by each member of the sales staff within the past 5 year period, \[{{x}_{2}}\] is the years of experience of each staff member and \[{{x}_{3}}\] is the number of glasses of wine each staff member drinks at lunch. Interpret the coefficients and the standard deviations for the following table for predictors \[{{x}_{1}}\], \[{{x}_{2}}\] and \[{{x}_{3}}\]. Suppose the printout displayed \[{{R}^{2}}=.31\]. What does that tell you? What can you say about a sales staff with regard to sales in general from these results?
