For a data set of brain volumes (cm") and IQ scores of nine males, the linear correlation coefmicient is r=0 946. Use the table available below to find the critical values of r Based on a comparison of the linear correlation coetticient r and the critical values, what do you conclude about a linear correlation? E Click the icon to view the table of critical values ofr. The critical values are (Type integers or decimals. Do not round. Use a comma t separate answers as needed.) Since the correlation coefficient ris v. there v sufficient evidence to support the claim of a linear correlation.
