Using excel for the scatter plot of price vs. square feet for the sample data. Plot square feet on the x-axis and price on the yaxis.
2. Based on the scatter plot, describe the relationship (if any) between square feet and price.
3. Use EXCEL to calculate the correlation coefficient and explain what it tells you about the relationship between square feet and price.
4. Use EXCEL to calculate the least-squares regression line (trend line) for the data. Write the equation.
5. Interpret the slope of the least-squares regression line. Specifically what does it tell you about the relationship between square feet and price?
6. Use the equation of the least-squares regression line from #4 to estimate how much you should charge for your home (which has 2,235 square feet). How does it compare with the price recommended by the real estate agent?
