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

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
