a) Plot the observed data on a scatterplot. b) Using the method of least squares, determine the equation for the estimated regression line using number of sessions missed to predict final grade. That is, calculate the values of the constant and regression coefficient. c) Write an interpretation of the estimated regression equation (i.e., what is the meaning of a, and what is the meaning of b?)
- The following data show the number of class sessions missed during a semester of SOC221 and the final grade for a sample of 8 students selected at random.
