A teacher believes that 85 percent of students in the class will want to go on a field trip to the local zoo.

She performs a hypothesis test to determine if the percentage is the same or different from 85 percent. The

teacher samples 50 students and 39 reply that they would want to go to the zoo. For the hypothesis test, use a

1 percent level of significance. First, determine what type of test this is, set up the hypothesis test, find the

p

value, and state your conclusion.
