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 usingalphaαequals=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, 358, 481, 530Crash Fatality Rate 15.8, 15.6, 15.4, 15.3, 14.9The linear correlation coefficient r isNext calculate the test statistic tThe P-value is
