Use a graphing calculator to plot the data and find the quadratic function of best fit.The following table shows the median number of hours of leisure time that Americans had each week in various years.
Use x = 0 to represent the year 1973. Using a graphing utility, determine the quadratic regression equation for the data given. What year corresponds to the time when Americans had the least time to spend on leisure?
What will be an ideal response?
M(x) = 0.04x2 - 1.21x + 26.03; 1988
