The relative frequency of correct responses can be calculated by dividing the number of correct responses by the total number of questions. Samantha got 20-4=16 questions correct.
Relative frequency = 16/20 = 0.8
Therefore, the relative frequency of correct responses is 0.8.
Relative frequency = 16/20 = 0.8
Therefore, the relative frequency of correct responses is 0.8.
