The table shows the average weekly wages (in dollars) for state government employees and federal government employees for 8 years. The equation of the regression line is y = 1.533x - 123.401. Complete parts (a) and (b) below. 758 770 794 838 887 916 951 Average Weekly Wages (state), x Average Weekly Wages (federal), y 807 1150 1000 1035 1106 1198 1245 1278 1307 C (a) Find the coefficient of determination and interpret the result. r² = 0.936 (Round to three decimal places as needed.) How can the coefficient of determination be interpreted? The coefficient of determination is the fraction of the variation in average weekly wages for federal government employees that can be explained by the variation in average weekly wages for state government employees 1-r -₁², is unexplained and is due to other factors or to sampling error. (b) Find the standard error of estimate se and interpret the result. Se = 30.62 (Round to two decimal places as needed.) How can the standard error of estimate be interpreted? The standard error of estimate of the average weekly wage for state government employees is about se dollars. and is represented by r². for federal government employees The remaining fraction of the variation, a specific average weekly wage for The table shows the average weekly wages (in dollars) for state government employees and federal government employees for 8 years.
