The generating time for an animal is the time it takes to reach reproductive maturity. The following data show the length 
, in feet, and the generation time 
, in years, for some animals.
Animal Deermouse Salamander Beaver Grizzly bear Elephant L 0.3 0.67 2.23 5.91 11.5 G 0.12 1 2.8 4 12.3? A: Use power regression to model the generation time as a function of the length. Use two digits of accuracy for the coefficient and for the power.B: Plot the data along with the power model you found in part A.C: According to the power model, if one animal is 3 times as long as another, how do their generation times compare? Round your answer to two decimal places.D: Does the grizzly bear have a longer or shorter generation time than would be predicted by the power model? What will be an ideal response?
