Find the regression equation, letting the first variable be the predictor (x) variable. Using the listed lemon/crash data, where lemon imports are in metric tons and the fatality rates are per 100,000 people, find the best predicted crash fatality rate for a year in which there are
500
metric tons of lemon imports. Is the prediction worthwhile?
Lemon Imports 
230 
270 
364 
461 
526 


Crash Fatality Rate 
16.1 
16 
15.7 
15.5 
15.2 
Find the equation of the regression line.
