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 + 0.19X5 + 26.8X6.
