Question
Transcribed Image Text: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?

The linear correlation coefficient is r=
(Round to three decimal places as needed.)
The test statistic is t=
☐
(Round to three decimal places as needed.)
The P-value is ☐
(Round to three decimal places as needed.)
Because the P-value is
than the significance level 0.05, there
significance level of α = 0.05.
