Do left-handed people have better analytical skills than right-handed people? Many nineteenth-century psychologists, extrapolating from discoveries made regarding brain lateralization, believed that they do. Some psychologists have recently uncovered an article that describes a study of chess players. The study reported such things as handedness and chess rating for the players. (A chess rating is a number from 100 to about 3000 , with a higher number indicating greater expertise.) The data for the 50 left-handed players studied are summarized in the following histogram: Frequency 15- 14 13 10- 6 5+ 1100 1500 Chess rating 300 700 1900 2300 2700 Based on the histogram, draw the ogive (the cumulative frequency polygon) for the sample data. Cumulative frequency 50 40 30 20 10 [0.00 0.00 [000 [0.00 0.00 0.00 [0.00 300 700 1100 1500 1900 2300 2700
