Find the regressionequation, letting the first variable be the predictor(x) variable. Using the listedlemon/crash data, where lemon imports are in metric tons and the fatality rates are per100,000 people, find the best predicted crash fatality rate for a year in which there are 475

475 metric tons of lemon imports. Is the predictionworthwhile?

Is the predictionworthwhile?

A.

Since common sense suggests there should not be much of a relationship between the twovariables, the prediction does not make much sense.

B.

Since all of the requirements for finding the equation of the regression line aremet, the prediction is worthwhile.

C.

Since there appears to be anoutlier, the prediction is not appropriate.

D.

Since the sample size issmall, the prediction is not appropriate.
