Researchers wondered whether the size of a person's brain was related to the individuals 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 141 190.000 (a) Draw a scatter diagram treating MRI count as the explanatory variable and IQ as the response variable Choose the correct diagram below. CA OB Oc 1.000.000 145 780.000 100.000 e) Draw a scatter diagram, but use a different plotting symbol for each gender. Choose the corect diagram below OA OB 780,000 1000000 1457 CEEEE 760.000 1.000.000 1.000.000 0000 (b) Compute the inear comelation coefficient between Mit count and IQ. Are Mic count and IQ nearly related? Select the correct choice below and, if necessary, 53 in the answer box to complete your choice Round to three decimal places as needed) OA No, MR count and 10 are not leearty related since the linear comelation coefficient s OB. Yes. Mount and iQ are nearly related since the lineer comelation coefficient is 1.000.000 100.000 AMI Females MRI 10 MRI 816.932 133 949,396 790.619 135 949,509 852 244 132 935,494 833,868 132 1,001,121 991,305 138 955,466 AUR 130 Males 145 19 140 144 (d) Compute the inear comelation coefficient between MRI count and 10 for females Compute the linear comelation coefficient between Mit count and 10 for males LO... 141 140 133 OD 410 145 1304 780.000 OD 1.000.000 AMIL 70 000-3 ddu
Yes MRI count and IQ are nearly related since the linear comelation coefficient is (e) Draw a scatter diagram, but use a different plotting symbol for each gender. Choose the corect diagram below OA 410 OB 145 130 160.000 1.000.000 4/0 Because the correlation coefficient for females females. Because the correlation coefficient for males is for males (Round to three decimal places as needed) What is the moral While MRI count and 10 are 145 780.000 00,000 Q a of and the absolute value of this comelation coefficient, and the absolute value of this correlation coefficient, OC (d) Compute the near correlation coefficient between MRI count and IQ for females. Compute the linear comelation coefficient between MRI count and 10 form The linear correlation coefficient for females The Snear correlation coefficient for mais Round to three decimal places as needed) Are Mic count and 10 inte for the population as a whole, MRI count and an AMU 1000007 180,000 130 than the critical value for the lemale data set than the ontical value for the male data set for each individual gender, OD AM 1.000.000 780.000 relation exists between Mit count and iQ for relation exists between Mit count and 10 Next
