Answer:

Duane's conclusion is wrong

Step-by-step explanation:

We can calculate the percentage scores by dividing the number of answers right by the total number of questions:

Science homework: 9/11 = 0.82, or 82%

History homework: 17/20 = 0.85, or 85%

So, Duane's conclusion is wrong because his percentage score for history was higher than the one for science.
