For a data set of brain volumes (cm) and IQ scores of seven males, the linear correlation coefficient is r = 0.868. 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 (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.
