Answer:

<em>The statement that is incorrect is :</em>

<em>Robert wanted to see if his theory was true that cigarette smoke will influence web-building in spiders.</em>

Explanation:

A theory can be described as a descriptive explanation of a phenomenon which is supported by valid experiments and careful examination of facts. As Robert, has not conducted any experiments nor has proved his study with reference to facts, hence it cannot be considered as a theory.

Robert wanted to see if his observation was true that cigarette smoke will influence web-building in spiders will be the correct statement that could be used.
