You wish to determine if there is a negative linear correlation between the two variables at a significance level of α=0.05. You have the following bivariate data set. x y 18.7 39.3 12.2 71.7 20.8...

You wish to determine if there is a negative linear correlation between the two variables at a significance level of α=0.05. You have the following bivariate data set.

What is the correlation coefficient for this data set?

r =


To find the p-value for a correlation coefficient, you need to convert to at-score:

t=√r2(n−2)1−r2

This
t-score is from at-distribution withn–2 degrees of freedom.


What is the p-value for this correlation coefficient?
p-value =
