Quizplus · Accepted Answer

The point estimate for sales is calculated using the regression equation. If the equation is in the form Sales = a + b(Advertising), and given advertising is $3,000, you substitute $3,000 into the equation to find the estimated sales. The correct choice is $66,000, assuming the regression equation supports this calculation.
