Solve the question with Mathematical Solution please.

An experiment was conducted on a chemical process that produces a polymer. The four factors studied were temperature $(A),$ catalyst concentration $(B),$ time $(C),$ and pressure $(D).$ The response is the molecular weight of the polymer. The design matrix and response data are shown in the following table.
