Learn the formula for the standard deviation and use it.
Or, even better, find online free of charge calculator.
Why the tutors should make these mechanical calculations for you ?

My response. I got this message in response to my solution.
I am not sure if this message came from you. If it is not from you, then ignore what follows.
We, the tutors, are in this forum not for doing calculations for students.
We are here to teach them to solve their problem.
Mechanical calculations (as in this case) is not our function.
For it, it is really better for you EITHER make them on your own,
OR to find an appropriate free of charge Internet online solver.
For example,

http://www.alcula.com/calculators/statistics/standard-deviation/
I am sure, it is the BEST advise which you can get.
And the last note for the future.
In average/regular day I respond 10-20-30 problems in this forum.
Therefore, if you want communicate with me productively, use the problem's ID number, referring to it. THANKS.
