a. Show a relative frequency distribution for the data on Drive.

b. plot a bar chart for the data on Fuel Type

c. Plot a side-by-side Bar chart for the two variables (Size and Fuel Type).

d. Prepare a crosstabulation of the data on Size (rows) and Hwy MPG (columns). Use classes of 1519, 2024, 2529, 3034, 3539, and 4044 for Hwy MPG.

e. Prepare a crosstabulation of the data on Drive (rows) and City MPG (columns). Use classes of 1014, 1519, 2024, 2529, 3034, and 3539, and 4044 for City MPG.
