Homework Help: probability and statistics

Posted by Tiffany on Tuesday, June 17, 2014 at 9:30pm.

Suppose every student in your class got a score of 85% on an exam. What are the mean and standard deviation of those exam scores without doing any calculations?

I want to say the mean is 100 and the standard deviation is 1 but I don't know why. If all students scored 85% that would be 100% of them so thats how I got 100 but I don't understand how to reach the standard deviation.
