Question: The table below lists brain sizes (in cm') and Wechsler IQ scores of subjects (based on data from Brain Size, Head Size, and Intelligence Quotient

The table below lists brain sizes (in cm') and Wechsler IQ scores of subjects (based on data from "Brain Size, Head Size, and Intelligence Quotient in Monozygotic Twins", by Tramo et al., Neurology, Vol. 50, No. 5). Brain Size 965 1029 1030 1285 1049 1077 1037 1068 1176 1105 IQ Score 90 85 86 102 103 97 124 125 102 114 1. Construct a scatterplot for the data. 2. Briefly characterize the correlation in words (such as "strong positive correlation" or "weak negative correlation"). 3. Use a calculator to compute the correlation coefficient. 4. Comment on the correlation between the two variables. Is there sufficient evidence to conclude that there is a linear correlation between brain size and IQ score? Does it appear that people with larger brains are more intelligent
