I need help finding the test statistic and the P-value

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 a = 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? 358 15.5 Lemon Imports Crash Fatality Rate 228 266 15.7 534 14.8 483 15.9 15.3 ..... VVIlal die ule iuii dilu dilemiduve iypouieses?
