Question

Decide whether the following statements makes sense for is clearly true) or does not make sense (or is clearly false). Explain your reasoning The relative frequency of B grades in our class was 0.3 Choose the correct answer below. O A. The statement does not make sense. Statements about relative frequencies only make sense when the total number of data values is given OB. The statement does not make sense. Relative frequencies must be integers, and 0.3 is not an integer Ос. The statement makes sense. Suppose there were 20 people in the class. If 4 received Bs and 2 received As, then the relative frequency of B grades was OD. The statement makes sense. Suppose there were 20 people in the class. If 6 received Bs, then the relative frequency of B grades was 03 0 3

Answer 1

The correct option is (D), i.e., The statement makes sense. Suppose there were 20 people in the class. If 6 received Bs, then the relative frequency of B grades was $\frac{6}{20}=0.3$ .

A relative frequency distribution shows the frequency of each class as a proportion or per-
centage of the whole data set.
