Students were given an exam with 300 multiple-choice questions. The distribution of the scores was normal and mean was 195 with a standard deviation of 30.

What was the score of students who scored in the middle of the class? (50% did better, 50% did worse).

The mean is 195. Is that the middle score of the class? I'm very confused. The text that I have is not showing how to solve this problem. AHHH

The distribution is normal, thus symmetric about the mean, so the mean is also the median. You are looking for the median.

So is the answer 195?
