Linear Regression & Correlation A sample of 6 children was selected. The values of their ages (-X- variable) and their weights (-Y- variable) are demonstrated in the table below. a) Compute the simple correlation coefficient (r) b) Find the regression equation and plot the fitted line c) Find the predicted weight when age is 8.5 years. Sample no. Age (X) Weight (Y) 1 9 14 2 6 10 3 5 9 4 8 13 5 11 6 7 6 12
