Moving times (in minutes) and weights (in pounds) were recorded for a random sample of 20 moving jobs requiring three-man crews, and the results of the regression analysis are shown below. The equation for the least squares regression line is:

Predicted time = 21.84 + 0.037(Weight)

Predicted weight = 21.84 + 0.037(Time)

Predicted weight = 25.54 + 0.003(Time)

Predicted time = 25.54 + 0.003(Weight)

Predicted time = 0.037 + 21.84(Weight)
