b. Find the linear correlation coefficient, r, then determine whether there is sufficient evidence to support the claim of a linear correlation between the two variables.

The linear correlation coefficient is r=

Hi Alex23E, welcome to the forum.

Check out **Math Is Fun's page on correlation.** It includes a nice example of how to compute the coefficient for a pair of data sets.

I believe so. The thing is that I just have to do this for like 10 more problems and don't have much time to do it I know with a graphing calculator it can be done very quickly but I don't have one
