A time-series plot titled "College Enrollment" has a horizontal axis labeled "Year" from less than 1989 to 2005 plus in increments of 1 and a vertical axis labeled "Percent Enrolled" from 58 to 70 in increments of 1. The following 17 points are plotted and connected from left to right by line segments: (1989, 59.4); (1990, 60.2); (1991, 61.6); (1992, 61.8); (1993, 61.8); (1994, 61.8); (1995, 62.4); (1996, 62.4); (1997, 63); (1998, 63.4); (1999, 64); (2000, 65.2); (2001, 65.6); (2002, 65.6); (2003, 66.8); (2004, 67.6); (2005, 68.6). All vertical coordinates are approximate.
