Plastic cases data

A materials engineer wants to understand the relationship between the strength of plastic cases and the temperature at which the strength measurements were made. The engineer suspects that the relationship between temperature and strength is quadratic, and wants to test for an interaction between supplier and temperature. The engineer collects 14 samples of plastic cases from Manufacturer A and 13 samples from Manufacturer B.

You can use this data to demonstrate Fit Regression Model.
