Archeology The data below show the length of the humerus and the total wingspan, in centimeters, of several pterosaurs, which are extinct flying reptiles of the order Pterosauria. (Source: Southwest Educational Development Laboratory.) a. Compute the linear regression equation for these data. b. On the basis of this model, what is the projected wingspan of the pterosaur Quetzalcoatlus northropi, which is thought tohave been the largest of the prehistoric birds, if its humerus is 54 centimeters? Round to the nearest centimeter. Pterosaur DataHumerus(cm)Wingspan(cm)20 50027 57015 30015 3109 2404.4 552.9 50Humerus(cm)Wingspan(cm)24 60032 75022 43017 37013 2704.4 683.2 531.5 24
