A university dining service offers the following four entres: pizza, cheeseburgers, quiche, and sushi. A sample of 500 students showed that 250 preferred pizza, 215 preferred cheeseburgers, 30 preferred quiche, and 5 preferred sushi. You want to know if there is a difference in preference among the four entrees. At the 1% level of significance I conclude that:

A. There is a significant difference in food choice preference among the student population.

B. There is not a significant difference in food choice preference among the student population.

C. Students prefer pizza over sushi.

D. None of the above.
