Amultiple regression analysis was performed to determine the relationship between the satisfaction rating for a new candy bar and the amount of chocolate used and the amount of caramel used. what is the mean value of the satisfaction rating, if the estimated regression equation is , the amount of chocolate (x1 ) used is 0.35 ounce, and the amount of caramel (x2 ) used is 0.15 ounce? a. 4.235 b. 6.73 c. 8.47 d. 50

The estimated rating is 8.2

Step-by-step explanation:

We are given the following information in the question:

The multiple regression line to determine the relationship between the satisfaction rating for a new candy bar and the amount of chocolate used and the amount of caramel used is given by:

where y is the satisfaction rating(dependent variable),

We have to find the mean estimated rating when the amount of chocolate used is 0.35 ounce, and the amount of caramel used is 0.15 ounce.

Putting the values, we get:

Thus, the estimated rating is 8.2
