For reasons of safety, a study of bears involved the collection of various measurements that were taken after the bears were anesthetized. When obtaining measurements from an anesthetized bear in the wild, it is relatively easy to use a tape measure to obtain the size of the chest, the length of the head, and the total length of the bear. It is difficult to find the weight because the bear must be lifted! Instead of actually weighing the bear, an estimate of the bears weight can be obtained from other measurements that were obtained. Use the data provided in cells E1 to H55 to answer the following questions. Head Length (HEADLEN) data is in cells E1 to E55. Length data is in cells F1 to F55. Chest size data is in cells G1 to G55. Weight data is in cells H1 to H55. All data sets have labels in first row. Develop the estimated regression equation that can be used to predict a bear's weight based on head length (HEADLEN), Length, and chest size. Place output in cell I1 Is the joint relationship significant using alpha .05? Are all the independent variables significant? why or why not? Interpret the coefficient for Head Length Is the model a good fit? Why or why not?
