Experience with a certain type of plastic indicates that a relationexists between the hardness (measure in Brinell units) of itemsmolded from the plastic (Y) and the elapsed time since terminationof the molding process (X). It is proposed to study this relationby means of regression analysis. A participant in the discussionobjects, pointing out that the hardening of the plastic \"is theresult of a natural chemical process that doesn\'t leave anything tochance, so the relation must be mathematical and regressionanalysis is not appropriate.\" Evaluate this objection.
