1. The record life span of an animal, in years, can supposedly be predicted by the average length of pregnancy, in days. The sample data given below is from the fifth edition of A Graphical Approach to PreCalculus with Limits by Hornsby, Lial, and Rockswold.

Life	26	24	15	17	6	49	50	29	12	22	15	16
Pregnancy	63	63	28	151	68	240	336	108	18	115	31	151

An elephant has an average pregnancy of 624 days. Should the regression equation (provided that it has passed the test of being the better predictor over in c) ) be used to make a prediction for the life span of an elephant in years? Why or why not?
