Use a scatterplot and the linear correlation coefficient r to determinewhether there is a correlation between the two variables.

Step 1

Step 2
Scatterplot suggest that there is a linear correlation between the variables.
[r=0.995]
$$\displaystyle{\left[{c}{r}{i}{t}{i}{c}{a}{l}-{r}=\pm{878}\right]}$$
Since absolute value of r is more than critical-r, hence there is a linear correlation between the variables.
