What is the correlation coefficient for this data set?
       r =
(report answer accurate to at least 3 decimal places)

To find the p-value for a correlation coefficient, you need to convert to a t-score:t=r⋅√n−21−r2t=r⋅n-21-r2This t-score is from a t-distribution with n−2n-2 degrees of freedom.

What is the p-value for this correlation coefficient?
       p-value =
(report answer accurate to at least 4 decimal places)

Your final conclusion is that...

There is sufficient sample evidence to support the claim that there is a statistically significant correlation between the two variables.
There is insufficient sample evidence to support the claim the there is a correlation between the two variables.
