Solve the problem.The following table shows the median number of hours of leisure time per week for Americans in various years.
Let f(t) be the median number of hours of leisure time at t years since 1993. Use a graphing calculator to draw a scatterplot to describe the data. Using the same viewing window, draw the graph of the quadratic model 
Use the model to estimate the years when the median number of hours of leisure time per week is 22.
What will be an ideal response?
The median amount of leisure time per week is 22 hours in 1997 and in 2019.
