a. Using the 10 points shown in the following table, find the equation of the line of best fit, yˆ = b0 = b1x and graph it on a scatter diagram.
b. Find the ordinates for the points on the line of best fit whose abscissas are x = 1,3, 5, 7, and 9.
c. Find the value of e for each of the points in the given data (e = y - yˆ)
d. Find the variancese2 of those points about the line of best fit by using formula (13.6).
e. Find the variance se2 by using formula (13.8). (Answers to parts d and e should be the same.)
