A cоmpаny mаnufаctures machine parts. The amоunt оf time it takes to fill an order depends on the number of parts in the order. In the table below we have five order summaries. The left number is the number of parts in the order. The right number is the number of labor hours it took to manufacture the parts. # Parts, Labor Hours Order 1: 40, 120 Order 2: 80, 310 Order 3: 20, 140 Order 4: 50, 200 Order 5: 100, 340 A regression analysis shows that r = 0.91 and the least squares regression line for predicting Y (hours to manufacture) from X (number of parts in order) is given by Y = 62.37 + 3.57*X What is the residual for Order 3?
