For a data set of brain volumes (cm) and I scores of eleven males, the linear correlation coefficient is r=0.671. Use the table available below to find the critical values of t. Based on a comparison of the linear correlation coefficient and the critical values, what do you conclude about a linear correlation? Click the icon to view the table of critical values of r.

Answer 1

for sample size n = 11 critical value of r is $\pm 0.602$

If r < negative critical value or r > positive critical value, then r is significant.

Since the correlation coefficient r is less than -0.602, there is sufficient evidence to support the claim of a linear correlation.
