Fitting a Line to Data The method of least squares is a standard approach to the approximate solution of overdeter- mined systems, i.e., sets of equations in which there are more equations than unknowns. The term "least squares" means that the overall solution minimizes the sum of the squares of the errors made in the results of every single equation. In this worksheet you will derive the general for- mula for the slope and y-intercept of a least squares line....

1. Identify the formula for predicting an individual's z score on the dependent variable from their z score on the independent variable. a.) (rxy)(zy) b.) (rxy)(zx) c.) zx/zy d.) (zx)(zy) 2. Data from the 1993 World Almanac and Book of Facts were used to predict the life expectancy for men in a country from the life expectancy of women in that country. The resulting regression equation was Yˆ = 9.32 + 0.79(X). Using the regression equation, what would you predict...
