The following table displays the top 40 American League batting averages of the last season. (See the Excel Data File.)
A) Construct frequency, relative frequency, and cumulative relative frequency distributions that group the data in classes of 0.265 up to 0.280, 0.280 up to 0.295, 0.295 up to 0.310, and so on.
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?
D) Construct an ogive.
E) Using the ogive, approximately what proportion of the players in this group has a batting average above 0.290?
