Managerial interpretation of estimated slope

Reference no: EM1398463

A local tire dealer wants to predict the number of tires sold each month. He believes that the number of tires sold is a linear function of the amount of money invested in advertising. He randomly selects 6 months of data consisting of tire sales (in thousands of tires) and advertising expenditures (in thousands of dollars). The equation of the least squares line is, y = 3 + 1x.
