Explanation of Solution
Given information:The table given below shows the gross revenue for Broadway season in different years:
Broadway Season Revenue | |
Year | Amount ($ millions) |
1994 | 406 |
1999 | 603 |
2004 | 769 |
2005 | 862 |
2006 | 939 |
2007 | 938 |
Calculation:
From part (a), the quadratic regression equation for the Broadway Season Revenue is
Consider that
Substitute 22 for x in the quadratic regression equation.
Therefore, the amount of gross revenue for the Broadway Season in year 2012 is 1228.15 millions of dollars.
