Listed below are annual data for various years. The data are weights (metric tons) of imported lemons and car crash fatality rates per 100,000 population. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value using =0.05. Is there sufficient evidence to conclude that there is a linear correlation between lemon imports and crash fatality rates? Do the results suggest that imported lemons cause car fatalities? Lemon Imports 230 264 357 480 531 = Crash Fatality Rate 15.9 15.6 15.5 15.2 14.8 Q Q Q Q 1 Q 16 5 - Q 16 - Q - Q 4 Lolsl o o9 lolg o % =z 15 = 15 = = = = X T1 X X X > 14 > 14 e g > 0 200 400 600 0 200 400 600 0 200 400 600 0 200 400 600 The linear correlation coefficientis r= (Round to three decimal places as needed ) The test statistic ist=| |.
