Question

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 475 metric tons of lemon imports. Is the prediction? worthwhile? Lemon Imports 229 267 362 485 517 Crash Fatality Rate 15.9 15.8 15.4 15.3 14.9 Find the equation of the regression line y = _ +? _x ?(Round the constant three decimal places as needed. Round the coefficient to six decimal places as? needed

Answer 1

equation of the regression line :Yhat=16.583+(-0.003018)*x

predicted crash fatality rate =16.583+(-0.003018)*475 = 15.149
