5. Major World Lakes A lake is a body of water surrounded by land. Hence, some bodies of water named “seas,” like the Caspian Sea, are actually salt lakes. In the table that follows, the length in kilometers is listed for the major natural lakes of the world, excluding the Caspian Sea, which has a length of 1,216 kilometers.

a. Use a stem and leaf plot to describe the lengths of the world’s major lakes.

b. Use a histogram to display these same data. How does this compare to the stem and leaf plot in part a?

c. Are these data symmetric or skewed? If skewed, what is the direction of the skewing?
