On the math test, Samantha missed 4 of the 20 questions. What is the relative frequency of correct responses?
A. 0.2
B. 0.8
C. 0.4
D. 0.16
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.
