(b) Evaluate MAP(1.5) and interpret the answer.

Exercise 1

Manufacturing—Average Costs: Consider the following data table for the cost and revenues at various production levels for a new brand of computer printer.

(a) Use your calculator to determine a linear regression model for the cost of producing the printer in the form

 C(x) = ax + b 1 ≤ x ≤ 4

where x represents the number of printers produced in thousands and C(x) represents the cost of production.

---

(b) Use your calculator to determine a cubic regression model for the revenue of producing and selling the printers in the form

 R(x) = ax3 + bx2 + cx + d 1 ≤ x ≤ 4

where x represents the number of printers produced and sold in thousands and R(x) represents the resulting revenue.

(c) Compute MAC(x) and simplify the result.

(d) Evaluate MAC(1.5) and interpret.
