A teacher believes that 85% 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%. The teacher samples 50 students and 39 reply that they would want to go to the zoo. For the hypothesis test, use a 5% level of significance. First, determine what type of test this is, set up the hypothesis test, find the p-value, sketch the graph, and state your conclusion. a. First, this is a test of a single population proportion.. b. Null and alternative hypotheses: c. Distribution of the test: d. Graph: e. Test statistic: f. p-value: g. Decision: h. Conclusion:
