b. Prepare a split stem-and-leaf display for the data. Split each stem into two parts. The first part should contain the leaves 0, 1, 2, 3, and 4, and the second part should contains the leaves 5, 6, 7, 8, and 9.
c. Which display (the one in part a or the one in part b) provides a better representation of the features of the distribution? Explain why you believe this.
