Raising In-State and Out-Of-State Tuition Is Supposed to Reduce the Number

Short Answer

Raising in-state and out-of-state tuition is supposed to reduce the number of students in state supported universities.The registrar of a university wants to estimate the proportion, $\pi$ ,of students who are paying out-of-state tuition on the installment plan (to later be compared with in-state installment plan payers).A random sample of 80 students who live out-of-state is taken and 50 of them pay tuition on the installment plan.Find a 99-percent confidence interval for $\pi$ based on these data.
