Interpreting the multiple regression analysis for the given MINITAB output

The district manager of Jasons, a large discount electronics chain, is investigating why certain stores in her region are performing better than others. She believes that 3 factors are related to total sales: the number of competitors in the region, the population in the surrounding area, and amount spent on advertising. From her district, consisting of several hundred stores, she selects a random sample of 30 stores. For each store she gathered the following information.

 

Y =

total sales last year (in $ thousands).

X1 =

number of competitors in the region.

X2 =

population of the region (in millions).

X3 =

advertising expense (in $ thousands).

 

The sample data were run on MINITAB, with the following results.
