Suppose we are calculating a multiple linear regression model where • The dependent variable is Sales (thousand $) The independent variables are • Advertising budget (thousand $) • Location (North/South/East/West) Suppose the coefficients table for the multiple linear regression model is given below. Estimate of coefficient p-value (intercept) 80 Less than 0.0001 budget (thousand $) 2.5 Less than 0.0001 South 10 Less than 0.0001 East -5 Less than 0.0001 West -2 0.75 TRUE or FALSE: After controlling for budget, there is not a statistically significant difference between sales in the West and sales in any other region. TRUE FALSE or not enough information
