Great Pumpkins: When growing giant pumpkins for competitions, growers need to keep track of the weights of the pumpkins while they are growing. It is difcult to weigh a large pumpkin before it is harvested, so a method has been developed for estimating the weight. The grower measures around the pumpkin both horizontally and vertically, then adds the results. This is called the O'I'I' (over the top) measurement and is used to predict the weight of the pumpkin. Following are the O'I'l' measurements and actual weights of the 10 largest pumpkins entered into ofcial competitions in a recent year. OTT (inches) Weight (pounds) 454.0 2138.9 450.0 2017.5 456.0 2077.0 465.0 2152.0 477.0 2157.5 469.0 2469.0 457.0 2079.0 451.0 2114.0 455.0 2283.0 454.0 2020.5(a) Compute the least-squares regression line for predicting weight 0)) from O'I'l' (x). Round the slope and y-intercept to four decimal places as needed. A The equation for the least squares regression line is y : D
