The college cafeteria manager claims that 90% of cafeteria customers are satisfied with the range of food

Question:

The college cafeteria manager claims that 90% of cafeteria customers are satisfied with the range of food served and prices. Suppose that in a random sample of 500 cafeteria customers, 438 say they are satisfied with the cafeteria. Does the sample result suggest that fewer than 90% of the cafeteria's customers are satisfied with the range of food served and prices?
