41.A researcher looks at predicting intelligence (IQ) using a person's brain size as a predictor. Intelligence is measured using a standard intelligence test and brain size is measured as the pixel count of a brain image taken using an MRI. The researcher calculates a linear regression equation with a constant of 5.36. The slope indicates that IQ increases 0.104 points for every 1 unit increase in pixel count. Using this regression model, calculate the predicted intelligence of a person with a brain size pixel count of 727. (Answer to three decimal places).
