A Sample of General Mills Employees Was Studied to Determine

A sample of General Mills employees was studied to determine their degree of satisfaction with
Their present life. A special index, called the index of satisfaction, was used to measure satisfaction.
Six factors were studied: age at the time of first marriage (X1) , annual income (X2) , number of
Children living (X3) , value of all assets (X4) , status of health in the form of an index (X5) , and the
Average number of social activities per week (X6) . Suppose the multiple regression equation is:
Y' = 16.24 + 0.017X1 + 0.00028X2 + 42X3 + 0.0012X4 + 0.09X5 + 26.8X6.
Explain the meaning of b5.

A) For each additional 10 points on the health status index, their satisfaction index is expected to increase by 9 points.
B) For each additional 10 points on the health status index, their satisfaction index is expected to increase by 0.09 points.
C) For each additional 10 points on the health status index, their satisfaction index is expected to increase by 0.9 points.
D) For each additional 10 points on the health status index, their satisfaction index is expected to drop by 0.09 points.
E) For each additional 10 points on the health status index, their satisfaction index is expected to decrease by 9 points.
