For a data set of brain volumes [cma'l and IQ scores of seven males, the linear correlation coet'licient is r= [1.422. Use the table available below to nd the critical values of r. Based on a comparison of the linear correlation coefcient r and the critical values, what do you conclude about a linear correlation? a Click the icon to view the table of critical values of r. The critical values are '1. (Type integers or decimals. Do not round. Use a comma to separate answers as needed.) Since the correlation coefcient r is T , there 7 sufcient evidence to support the claim of a linear correlation.
