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 alpha= 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 231 264 359 482 531
Crash Fatality Rate 15.9 15.7 15.4 15.2 14.8
There scatter diagram suggests that there exists a negative correlation between two variables.
Conclusion:
There is sufficient evidence to conclude that there is a linear correlation between lemon imports and crash fatality rates.
Yes , the results suggest that imported lemons cause car fatalities.
