Tray seal data

A clean room engineer analyzes a response surface design to determine how seal time, temperature, and pressure affect the seal quality of the sealed trays. The response is binary-whether the seal is intact or not-in a sample of 800 tray seals.

You can use this data to demonstrate Analyze Binary Response for Response Surface Design.
