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 1,080.000 100,000 (a) Draw a scatter diagram treating MRI count as the explanatory variable and IQ as the response variable.

Are MRI count and IQ linearly related? Select the comect choice below and, if necessary, fill in the answer box to complete your choice. (Round to three decimal places as needed) OA No MRI count and 10 are not inearty related since the linear correlation coefficient is OB Yes, MF count and 10 are inearly related since the linear comelation coefficient is 1,000,000 240.000 856,472 140 857,762 133 852 244 132 951.545 137 AME 100.000 130 10 132 145 TM (124 Males MRI IQ 965.353 133 955,003 139 1,001,121 140 924,059 135 1,079,550 141 LILI (d) Compute the inear correlation coefficient between Mit count and IQ for females.
