The summary statistics for number of Facebook friends and measure of grey matter density are listed below. The correlation between number of Facebook friends and measure of grey density matter is 0.3329. Measure of grey matter density: mean = -0.0829, standard deviation = 0.9329 Number of Facebook friends: mean = 354.1714, standard deviation = 171.6876 3. The equation for the regression line is y = X Round your answers to 6 decimal places. 4.Complete the following sentence to interpret the slope of the regression line: An increase of 1.0 in grey matter density corresponds to a/an increase v of in number of Facebook friends. 5. Subject A has a recorded grey matter density of -0.9. Use the regression equation to estimate the number of Facebook friends for this individual. 6. The number of Facebook friends for Subject A is 472. Complete the following sentence: The residual for Subject A is . This means the number of Facebook friends for Subject A is OA. the same as OB. lower than O C. higher than the number of Facebook friends predicted by the regression model. 7. Another individual (not included in this data set) has a grey matter density of 2.5. Would it be appropriate to use this linear model to predict the number of Facebook friends for this individual?
