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. $\begin{array}{l|lllll}
\text { Year } & 1973 & 1980 & 1987 & 1993 & 1997 \
\hline \text { Median \# of Leisure hrs per Week } & 26.2 & 19.2 & 16.6 & 18.8 & 19.5
\end{array}$
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?
