For a simple linear regression analysis attempting to relate consumer confidence (y) to the unemployment rate (x), the following data are available:
Show the data in a scatter diagram and use the least squares criterion to find the slope (b) and the intercept (a) for the best fitting line. Sketch the least squares line in your scatter diagram. Use the line to predict the change in the consumer price index that would be associated with a two point jump in the unemployment rate.
