compute the linear correlation coefficient between MRI count and IQ. Or MRI count an IQ linearly related? Select the correct choice below and if necessary fill in the answer box to complete your choice. Round to three decimal places as needed.

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 counts and IQ scores. The data is reported to the right.

(b) Compute the linear correlation coefficient between MRI count and IQ. Are MRI count and IQ linearly related? Select the correct choice below and, if necessary,
fill in the answer box to complete your choice.
(Round to three decimal places as needed.)
O A. Yes, MRI count and IQ are linearly related since the linear correlation coefficient is
O B. No, MRI count and IQ are not linearly related since the linear correlation coefficient is
