A recent study of 50 U.S. chess players details such things as the number of years the players have been active and the chess ratings of the players. (A chess rating is a number, with a higher number indicating greater expertise.) The chess rating data for the sample of 50 players are summarized in the following histogram. Frequency 154 10- 5- 300 15 700 1100 1500 Chess rating Based on the histogram, draw the ogive (the cumulative relative frequency polygon) for the sample data. Cumulative relative frequency 7 1900 2300 2700
