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

question 57

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.

Wye-Delta Transformer

A transformer configuration used to shift between high and low voltages in a three-phase electrical system, involving a star (Wye) connection and a delta connection.

Wye

A configuration in electrical engineering where three phase circuits are connected at a single point, forming a 'Y' shape, allowing for both three-phase and single-phase connections.

Delta

A method of connecting three electrical components in a triangular configuration, allowing for the completion of a circuit without a neutral path.

Open Delta

A connection method for three-phase transformers where only two transformers are used, providing a way to supply three-phase power with reduced capacity.
