In a study of feeding behavior, zoologists recorded the number of grunts of a warthog feeding by a lake in the 15 minute period following the addition of food. The data showing the number of grunts and and the age of the warthog (in days) are listed below: Number of Grunts Age (days) 90 125 68 141 39 155 44 160 63 167 40 174 62 183 17 189 20 195 Write the equation of a straight-line model relating number of grunts (y) to age (x). b. Give the least squares prediction equation. c. Give a practical interpretation of the value of 50, if possible. a. d. Give a practical interpretation of the value of 51, if possible.
