  1. The shape of the distribution is right skewed.
  2. Compute the sample statistics mean, median, standard deviation, variance, range. Compare the mean and median; what do they tell you about the shape of the distribution?  The mean and median did not appear to really change when I included the mean, median, standard deviation, variance, and range.  According to the book, the median is a better measure of central tendency when dealing with skewed data, but the mean is the balancing point of the histogram.  From the data we can determine that the cars that appear to sell the most are the cars that are not marked up as much for a higher profit for the dealership.
