The scores on four variables for 20 individuals are reported here: hours of TV (average number of hours of TV viewing each day), occupational prestige (higher scores indicate greater prestige), number of children, and age. Take TV viewing as the dependent variable and then select two of the remaining variables as independent variables.

a. Compute beta-weights for each of the independent variables you selected and then compare their relative effect on the hours of television watching. Which was the more important factor?

b. Compute R and R².
