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. 780.000 130 IQ 145 G Because the correlation coefficient for females is females. Because the correlation coefficient for males is for males. (Round to three decimal places as needed.) What is the moral? 130 780,000 1.080,000 While MRI count and IQ are MRI C and the absolute value of this correlation coefficient, is and the absolute value of this correlation coefficient, for the population as a whole, MRI count and IQ are Females MRI 10 MRI IQ 951,545 137 1,079,550 141 816,932 133 955,466 133 833,868 132 955,003 139 790,619 135 1,038,438 139 866,662 130 965.353 133 (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 The linear correlation coefficient for males is. (Round to three decimal places as needed.) Are MRI count and IQ linearly related? 3000 130- 780.000 1,080,000 Is MRI Males ▼ for each individual gender. D ▼than, the critical value for the female data set, than the critical value for the male data set, 780,000+ la 145 C relation exists between MRI count and IQ for relation exists between MRI count and IQ
