C. 0.4
D. 0.16

1 answer

The relative frequency of correct responses can be calculated by dividing the number of correct responses by the total number of questions.

Since Samantha missed 4 out of 20 questions, she answered 16 out of 20 questions correctly.

Relative frequency of correct responses = 16/20 = 0.8

Therefore, the relative frequency of correct responses is 0.8, so the answer is B. 0.8.
