Testing for a Linear Correlation. In Exercises 13–28, construct a scatterplot, and find the value of the linear correlation coefficient r. Also find the P-value or the critical values of r from Table A-6. Use a significance level of æ = 0.05. Determine whether there is sufficient evidence to support a claim of a linear correlation between the two variables. (Save your work because the same data sets will be used in Section 10-2 exercises.)

I would need some assistance with problem nineteen, please?

19. Lemons and Car Crashes Listed below are annual data for various years. The data are
weights (metric tons) of lemons imported from Mexico and U.S. car crash fatality rates per
100,000 population [based on data from "The Trouble with QSAR (or How I Learned to Stop
Worrying and Embrace Fallacy)," by Stephen Johnson, Journal of Chemical Information and
Modeling, Vol. 48, No. 1]. Is there sufficient evidence to conclude that there is a linear correla-
tion between weights of lemon imports from Mexico and U.S. car fatality rates? Do the results
suggest that imported lemons cause car fatalities?
