(d) Compute the linear correlation coefficient between MRI count and IQ for females. Compute the linear correlation coefficient between MRI count and IQ for males. The linear correlation coefficient for females is 0.533. The linear correlation coefficient for males is 0.477. (Round to three decimal places as needed.) Are MRI count and IQ linearly related? Because the correlation coefficient for females is 0.533, is between MRI count and IQ for females. Because the correlation coefficient for males is absolute value of this correlation coefficient, is relation exists between MRI count and IQ for males. (Round to three decimal places as needed.) and the absolute value of this correlation coefficient, than 0.477, the critical value for the female data set, relation exists and the than the critical value for the male data set,

Researchers wondered whether the size of a person's brain was related to the individual's mental capacity. They selected a sample of 5 females and 5 males and measured their MRI image pixel counts and IQ scores. The data is reported to the right. Complete parts (a) through (d) below. Click the icon to view the critical values table. Females The linear correlation coefficient for females is 0.533. The linear correlation coefficient for males is 0.477.
