Suppose we wonder how pay scale affects job performance. We randomly select six new employees with similar experience and skills and randomly pay them each different amounts. We then evaluate their job performance after three months. The data is as follows: Person Pay Performance A 20 75 B 20 85 C 30 80 D 30 85 E 40 95 F 40 90 (by hand) Do the following on paper, using a calculator. You don't need to turn this in, but this is practice and may be covered on a quiz at some point or on the exam. - Make a scatterplot for the data, and draw a possible regression line. - Draw vertical line segments that represent the residuals. - - - Based on your eye, estimate the intercept, slope and equation of the line. Use this equation to make a column of fitted values for the six people. - Make a column for the residuals. - Find n, df, SSE, MSE, E.
