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 Crash Fatality Rate 15.9 15.7 225 261 357 15.3 492 529 O 15.4 14.9 (Round the yintercept to three decimal praces as needed. Round the stope to Tour decimar piaces as needed. The best predicted crash fatality rate for a year in which there are 500 metric tons of lemon imports is (Round to one decimal place as needed.) fatalities per 100,000 population. Is the prediction worthwhile? O A. Since common sense suggests there should not be much of a relationship between the two variables, the prediction does not make much sense: O B. Since all of the requirements for finding the equation of the regression line are met, the prediction is worthwhile. O C. Since the sample size is small, the prediction is not appropriate. O D. Since there appears to be an outlier, the prediction is not appropriate.
