(Problem 16.23) Draw a spider plot for the level of demand in year 5 (halfway through the 10-year horizon) when L = 1000 ± 20%, year 1's demand ranges from 4 to 10, and year 2's demand ranges from 40 to 70.
(a) Assume a Pearl curve.
(b) Assume a Gompers curve.
Problem 23
Calculate and draw growth curves over 10 years. Let L = 1000 and the numbers for years 1 and 2 be 5 and 50, respectively.
(a) Calculate the coefficients, and draw a Pearl curve.
(b) Calculate the coefficients, and draw a Gompers curve.
(c) Contrast the two curves. Is there any basis for preferring one of them?
