B) How many of these players have a batting average above 0.340? What proportion of these players has a batting average of at least 0.280 but below 0.295? What percentage of these players has a batting average below 0.325?
C) Construct a relative frequency histogram. Is the distribution symmetric? If not, is it positively or negatively skewed?
