A regression analysis between sales (y in $1000) and advertising (x in $100) resulted in the following least squares line: y = 82 + 7x. a)This implies that if advertising is $900, then the predicted amount of sales (in dollars) is: b)Which is the most appropriate interpretation of the intercept of the estimated regression line given above?

However, we are given that the regression analysis resulted in the following least squares equation: y = 20 + 4x where y is sales in $1000 and x is advertising in $100. Show more…

A regression analysis between sales (x) and advertising (y) resulted in the following regression line: y' = 75 + 6x. This implies that if advertising is $15,480, then the predicted amount of sales (in dollars) is: a. $2,592.50 b. $2,655 c. $92,955 d. $92,805 e. $2,567.50

A regression analysis between sales (y in 1000 dollars) and advertising (x in 100 dollars) resulted in the following least-squares line: Ĺ· = 82 + 7x. Given this information, if advertising costs were 900 dollars, what could we reasonably expect the amount of sales (in dollars) to be?

A regression analysis between sales (in $1000) and advertising (in $100) resulted in the following least squares line: yhat = 75 + 6x. This implies that if advertising is $800 (i.e. x=8), then the predicted amount of sales (in dollars) is: Hint: Multiply from the equation by $1000. $4,875 $123,000 $487,500 $12,300
