The data in Exercises 21–24 are from the Bureau of Labor Statistics.
For people over the age of 16 who were unemployed during November of the years listed, the table gives the average number of weeks those people were unemployed as of November.
On the basis of these data, a statistician suggests that the following formula can be used to approximate the average number W of weeks given in the table:
\(W=-0.1 x^{2}+0.27 x+18.15\)
where x = 2 corresponds to 1992, x = 3 corresponds to 1993, and so on.
(a) Use this formula to compute W for each of the years 1992 through 1997.
(b) Compare the values collected by the Department of Labor with the values obtained from the formula, and comment about the accuracy of the formula.
