Calculate the average growth rate per year in enrollments over the two periods 1960–1965 and 2006– 2009. Note that the time periods are not of the same length. 23. This exercise uses the results of Exercise 22. Use your results from Exercise to determine during which period, 1960–1965 or 2006–2009, the enrollments grew more quickly on average. Relate your answer to the steepness, or slope, of the corresponding line segments.
