a. Determine the equation for the line of best fit using your graphing
calculator. Round the slope and y-intercept to two decimal places.
b. Use your equation to estimate the undergraduate tuition for the 2009-2010
school at Yale. Round your answer to the nearest dollar.
c. Ask your chaperone for the article about Yale's
2009-2010 costs. Read the article carefully to find the amount of the
tuition only (not the total cost including room and board). What is
the percent of error between your estimate above and the actual tuition?
