这是题
We will begin our use of regression with modelling a revenue function for Woody's restaurants (see Studenmund). The data is in woody.xls. The dependent variable is annual sales turnover at Woody's restaurants and the independent variables are the number of competitors in the local market, the population in the local market and the average household income in the local market area. (Price is not a relevant variable because the pricing structure is the same at all of the restaurants.)

Interpret the results (All regression estimates i.e., respect to estimated coefficients, their significance, overall model fit)
