Answer:
Wrong Picture. Based on Picture, about 62.5%
Step-by-step explanation:
We see that there are 8 dots. The question asks for students who answered 15 or more correct, so any students who answered 15 or above. We see that from 15 to 18, there are 5 students. So, [tex]\frac{5}{8}=0.625=62.5[/tex]%. This matches none of the answers, and the picture does not match the question, so you posted the wrong picture.
