Researchers wondered whether the size of a person's brain was related to the individual's mental capacity. They selected a sample of 3 females and 3 males and measured their MRI counts and IQ scores. The data is reported on the right. Females Males MRI IQ MRI IQ T90,E20 135 1,038,433 138 856,564 132 955.355 132 856,473 141 9211,1160 138 % Treat the MRI count as the explanatory variable. Compute the linear correlation coefcient between MRI count and IQ for both the males and the females. Do you believe that MRI count and ID are linearty related? The linear correlation coetficient for females is :l. The linear correlation coetficient for males is :l. (Round to three decimal places as needed.)
