The table below includes data from taxi rides. The distances are in miles, the times are in minutes, the fares are in dollars, and the tips are in dollars. Is there sufficient evidence to conclude that there is a linear correlation between the time of the ride and the tip amount? Construct a scatterplot, find the value of the linear correlation coefficient $r$, and find the $P$-value of $r$. Determine whether there is sufficient evidence to support a claim of linear correlation between the two variables. Use a significance level of $\alpha=0.01$. Does it appear that riders base their tips on the time of the ride?

Construct a scatterplot. Choose the correct graph A.
Determine the linear correlation coefficient. The linear correlation coefficient is $\mathrm{r}=$ $\square$ (Round to three decimal places as needed.)
