Dr. Hincapie wants to test the hypothesis that stress increases one's blood pressure. What type of hypothesis is Dr. Hincapie interested in testing?

The question is incorrect as it does not have the option which are:

a. Predictive

b. Causal

c. Correlational

d. Biological

Answer:

B) Causal hypothesis

Explanation:

A causal hypothesis is a theory or an idea which states how the things interact with each other and how one thing can cause another thing or in simple terms its is "this causes that".

The purpose of the formation of the causal hypothesis is to test ad reject the given causal hypothesis.

In the given question, since the effect of stress on the blood pressure is studied or how the stress causes an increase in the blood pressure is discussed therefore the hypothesis is a type of the causal hypothesis.

Thus, Option-B is the correct answer.
