The college cafeteria manager claims that 90 of cafeteria customers
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? You have already examined this problem, in Chapter 6 Review Exercise 4. Complete a formal hypothesis test. Use α = 4%.
