Question

For a data set of brain volumes (cm³) and IQ scores of twelve males, the linear correlation coefficient is r = 0.822. 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?
