I have a table full of heads
Each head took a test and the only thing I know about the test of each head are their results
The results show the total number of questions and the number of correct answers
Each head has a different total number of questions
I have to select the most intelligent head
Q=total number of questions
one head took only 1 question and got it correct, other head took 4 and 3 were correct, is second head more intelligent than first?
what can I do?
