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 difficult 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'l'l' (over the top) measurement and is used to predict the weight of the pumpkin. Following are he O'l'l' measurements and actual weights of the 10 largest pumpkins entered into official competitions in a recent year. 0TT(inches) Weight(pounds) 154.0 2138.9 156.0 2077.0 450.0 2017.5 1 73.0 2166.0 469.0 2469.0 462.0 2070.1 136.0 2027.0 154.0 2020.5 165.0 2152.0 451.0 2114.0 Send data to Excel Partlof4 8 Compute the leastsquares regression line for predicting the weight(y) from O'l'l'(x). Round the slope and yintercept to at least four decimal places. A y: Regression line equation: Correct Answer: Part2 of4 Is it possible to interpret the y-intercept? Explain. F V , the x-values must be 7 . Part3 of4 If two pumpkins differ in O'l'l' by 8 inches, by how much would you predict their weights to differ? Round the answer to three decimal places. The weight would differ byl l pounds. Part4 of4 Predict the weight of a pumpkin whose O'I'l' is 480 inches. Round the answer to one decimal place. The weight is predicted to be pounds
