  1. Make a scatter plot, including the regression line and its equation.
  2. Use an appropriate Excel function to find the correlation coefficient r. Determine the type of linear relationship, if any.
  3. Interpret the slope and y-intercept, if appropriate, in the context of the data.
  4. Use an appropriate Excel function and the data to find a predicted(average) selling price for a single- family house measuring 1960 square feet. Does the house that measured 1960 square feet in the sample have a selling price that is below or above average, and why?
