Table 1.5 shows the gross revenue for the Broadway season in millions of dollars for several years.

(a) Find the quadratic regression for the data in Table 1.5. Let x = 0 represent 1990, x = 1 represent 1991, and so forth.

(b) Superimpose the graph of the quadratic regression equation on a scatter plot of the data.

(c) Use the quadratic regression to predict the amount of revenue in 2008.

(d) Now find the linear regression for the data and use it to predict the amount of revenue in 2008.
