Find the standard error of the estimate and the coefficient of determination for the least-squares regression line y = b0 + b1x through the points (-1, 1), (0, 6), (5, 13), (7, 19), (11, 25). Standard Error of the Estimate Coefficient of Determination

Find the Root Mean Square Error (RMSE) and the coefficient of determination for the least-squares regression line y = bx through the points (-3, 2), (3, 9), (6, 15), (9, 18), (12, 23). Root Mean Square Error (RMSE): to three decimal places Coefficient of Determination: to three decimal places

(5 points) For the least-squares regression line fit Y = Bo + B1X1 + B2X2 through the (X1, X2, Y) points (-2.9, -0.6, 5.2), (2.7, 2.2, 5.7), (4.8, 2.5, 18.8), (7.6, 4.1, 34.5), (10.8, 5.7, 48.3). Construct the ANOVA table (Give the p-value to two decimal places accuracy). To three decimal places, the value of the coefficient of multiple determination is R2
