The U.S. Department of Energy's Fuel Economy Guide provides fuel efficiency data for cars and trucks. A portion of the data from 2018 for 341 compact, midsize, and large cars is shown in the following table.

Car	Size	Displacement	Cylinders	Drive	Fuel Type	City MPG	Hwy MPG
1	Compact	1.4	4	F	R	27	40
2	Compact	1.4	4	F	R	27	35
3	Compact	1.4	4	F	R	28	38
190	Compact	2.5	4	F	R	27	36
191	Large	2.5	4	F	R	22	30
192	Midsize	2.5	4	F	R	21	32
339	Large	6.0	12	R	P	13	21
340	Large	6.0	12	R	P	13	22
341	Large	6.0	12	R	P	13	20

The data set contains the following variables.

• Size: Compact, Midsize, and Large
• Displacement: Engine size in liters
• Cylinders: Number of cylinders in the engine
• Drive: All wheel (A), front wheel (F), and rear wheel (R)
• Fuel Type: Premium (P) or regular (R) fuel
• City MPG: fuel efficiency rating for city driving in terms of miles per gallon
• Hwy MPG: fuel efficiency rating for highway driving in terms of miles per gallon

The complete data set is contained in the file named FuelData2018.(a)Construct a crosstabulation of the data on Size (rows) and Hwy MPG (columns). Use classes of 20-24, 25-29, 30-34, 35-39, and 40-44 for Hwy MPG.
