Given are five observations for two variables, and y. 24 1 2 N 3 4 5 Yi 4 UT 5 8 11 15 Scatter diagram #2 d. Develop the estimated regression equation by computing the values of bo and by using Equation 14.6 and Equation 147 (to 1 decimal). z e. Use the estimated regression equation to predict the value of y when 4 (to 1 decimal) SLOPE AND Y-INTERCEPT FOR THE ESTIMATED REGRESSION EQUATION (x - xly; - y) b = (x - ) (14.6) (14.7 bo = - bi where X;= = value of the independent variable for the ith observation Y; = value of the dependent variable for the ith observation f = mean value for the independent variable y = = mean value for the dependent variable n = total number of observations
