Question

for a data set of brain volumes (cm³) and iq scores of six males, the linear correlation coefficient is r = 0.866. use the table available below to find the critical values of r. based on a comparison of the linear correlation coefficient r and the critical values, what do you conclude about a linear correlation? click the icon to view the table of critical values of r. the critical values are - 0.811,0.811 (type integers or decimals. do not round. use a comma to separate answers as needed.) since the correlation coefficient r is, there sufficient evidence to support the claim of a linear correlation.

Explanation:

Step1: Recall correlation - critical - value rule

If $|r|>r_{critical}$, there is a linear correlation. Here $r = 0.866$ and $r_{critical}=0.811$.

Step2: Compare values

Calculate $|r|=|0.866| = 0.866$. Since $0.866>0.811$.

Answer:

greater than the critical value, is
