Suppose That I Have a Randomly Selected Sample of 42

Essay

Suppose that I have a randomly selected sample of 42 American men. In this sample, the average number of hours worked per week is 45 with a standard deviation of 12. The average level of life satisfaction (on a scale from 1 = "hating life" to 10 = "loving life) is 5.00 with a standard deviation of 3.00. The correlation between hours worked and life satisfaction is .40. Please answer the following two questions based on these data.
a. If you know that someone works 35 hours per week, what would you predict her life satisfaction score to be? (Please provide enough information so that I can tell how you reached your conclusion, including your regression coefficient and your intercept).
b. Please wrap words around the regression coefficient that you calculated for the last problem. What does this tell you?
