II.2. Quarterbacks. Table II.2 gives the total passing yards for National Football League starting quarterbacks during the 2014 season. (These are the quarterbacks with the most passing yards on each team.) Make a histogram of these data. Does the distribution have a clear shape: roughly symmetric, clearly skewed to the left, clearly skewed to the right, or none of these? Which quarterbacks (if any) are outliers?
