<h3>What is Standard Deviation and Mean?</h3>
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.
The mean can be used to get an overall idea, or picture, of the data set.
Let Mean be 'm'
and standard deviation= 
So, m-2
=49
and, m +
=61
Solving the above two equation we get

Now, m= 61-
= 61-4
= 57
So , the mean of this test will be =57

hope that helped
Since they gave you the boxes you need the first number to be zero therefore having the quotient starting with zero. Then you may divide normally
