A consulting group surveyed General Mills, Inc. employees to research the factors that affect their satisfaction with their quality of 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 weekâ€"such as bowling and dancing (X6). Suppose the multiple regression equation is:
What is the estimated index of satisfaction for a person who first married at 18, has an annual income of $26,500, has three children living, has assets of $156,000, has an index of health status of 141, and has 2.5 social activities a week on the average? (Round your answer to 3 decimal places.)
Which values would add more to satisfaction, an additional income of $10,000 a year or two more social activities a week? (Round your answers to 1 decimal place.)
The weight of a block of metal is measured with a scale first in air, then in water. Find the specific gravity of the metal ( the ratio of the density of metal to the density of water). The tension of the block is measured 6.0N in air and 4.0N in wa..
