Step-by-step explanation:

Given that:

The National Institutes of Health has recommended that the healthy adults are to take at least 50 nmol/L of vitamin D per day. Let’s assume that you are interested in discovering if the BSU students are suffering from vitamin D deficiency or not.

a) Formulate the appropriate null and alternative hypotheses

Null hypothesis

H o : u >= 50

Alternative hypothesis

Ha : u < 50
