Sports salaries. Refer to Table 4.

(A) Let x represent the number of years since 1990 and find an exponential regression model for the average salary in the NBA. Use the model to estimate the average salary (to the nearest thousand dollars) in 2020.

(B) The average salary in the NBA in 1997 was $2.2 million. How does this compare with the value given by the model of part (A)? How would the inclusion of the year 1997 data affect the estimated average salary in 2020? Explain.
