A Regression Analysis Between Y, Sales (In $1000) and X $\ddot { p }$

question 171

True/False

A regression analysis between y, sales (in $1000) and x, advertising (in $) yielded the least squares line $\ddot { p }$ = 60 + 5x. We can interpret the slope by saying that we estimate for each extra $1 spent on advertising that sales will increase by $5 000, on average.
