Question: A psychologist is interested in the relationship between brain size and intelligence. A series of measurements of the size of the brain using an MRI were conducted along with IQ testing. Run a regression analysis to determine if the Full Scale IQ and size of the brain (MRIcount) are related. From this analysis what would the predicted brain size be of someone who had a FSIQ of 120? (20 pts)

The following table shows the results of the study.

Gender	FSIQ	VIQ	PIQ	Weight	Height	MRIcount
