ram Some psychologists interested in the relationship between handedness (being right-handed or left-handed) and analytical ability have recently uncovered an article from a monthly publication on chess that describes a study of U.S. chess players, with the study reporting such things as handedness and chess rating. (A chess rating is a number from 100 to about 3000, with a higher number indicating greater expertise.) In the article, the data for the 43 left-handed players studied are summarized in the following histogram: Frequency 12 12 10- 8- 6 6 6- 4- N 300 700 1100 1500 1900 2300 2700 Chess rating From the histogram, estimate the mean chess rating for the left-handed players in the study. Carry your intermediate computations to at least four decimal places, and round your answer to at least one decimal place. X
