The statement/claim/hypothesis in a question is our [ Select ] ["alternative (H1)", "null (H0)"] hypothesis.

For instance: "The professor of a class claims that the mean final ex*m score of the class will be greater than 75".

Let's formulate the null hypothesis as H0: Mean Final Ex*m Score [ Select ] ["<", "", "", "", "=", ">"] 75.

Let's formulate the alternative hypothesis as H1: Mean Final Ex*m Score [ Select ] ["", "", "<", "=", ">", ""] 75.

Formulate H0 (null) and H1 (alternative ) hypotheses using the given statement below.
