10 points) National Institutes of Health recommends that the healthy adults take at least 50 nmol/L of vitamin D per day. Suppose that you are interested in finding out if the BSU students are suffering from vitamin D deficiency or not. (a) (5 points) Formulate the appropriate null and alternative hypotheses. Clearly define the parameter of interest in the context of the problem.

Check the explanation

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

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
