For a data set of brain volumes (cm³) and IQ scores of twelve males, the linear correlation coefficient is r = 0.775. 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? The total number of samples is 9.

Step 1
Given that the total number of samples is 12, the degrees of freedom (df) is calculated as df = n - 2 = 12 - 2 = 10. ** Show more…

The linear correlation coefficient $r$ is provided. Use Table 2-11 on page 71 to find the critical values of $\boldsymbol{r} .$ Based on a comparison of the linear correlation coefficient rand the critical values, what do you conclude about a linear correlation? Using the data from Exercise 8 "Heights of Fathers and Sons," the linear correlation coefficient is $r=-0.017$
