Table P-18 gives weekly wages (WAGES) in dollars and length of service (LOS) in months, at a specific point in time, for 16 women who hold customer service jobs in Texas banks

a. Plot the data in Table P-18 as a scatter diagram with WAGES along the vertical (Y) axis and LOS along the horizontal (X) axis.
b. Calculate the sample correlation coefficient, r. Using the sign and magnitude of r, describe the nature of the linear association between WAGES and LOS. Can you think of other variables that might affect weekly wages in addition to length of service?
c. Calculate the fitted line that can be used to predict WAGES from LOS. If LOS is 80 months, what is the predicted WAGES?
