**Understanding Cumulative Relative Frequency in Public College Enrollment**The cumulative relative frequency plot displayed uses data on the percentage of college students enrolled in public institutions across the 50 U.S. states. The question asks which of the following options is closest to the approximate proportion of states that have more than 70 percent of college students enrolled in public institutions:a. 0.1 b. 0.2 c. 0.4 d. 0.7 e. 0.8 **Graph Explanation:**The graph depicts the cumulative relative frequency on the vertical axis, ranging from 0.0 to 1.0, against the percentage enrolled on the horizontal axis, spanning from 40% to 100%. Key observations include:- At 70% enrollment, the cumulative relative frequency is approximately 0.4.- Beyond 70% enrollment, the cumulative frequency increases, reaching around 0.8 by the time it hits 100% enrollment.This suggests that the proportion of states with more than 70 percent of students enrolled in public institutions is approximately 0.8 (answer choice e).
