You can put this solution on YOUR website! .
Regarding standard deviation, go to web-site
https://www.calculator.net/standard-deviation-calculator.html
Find an online free of charge calculator there, along with the nice
professional and educational descriptions of this notion and the formula/formulas.
Use it and get the answer on your own.
In parallel, learn from this web-site all relevant information related to the method of calculations.
By the way, it is written in your textbook (and everywhere else),
so I do not understand why do you require the tutors to make these
simple mechanical calculations for you, instead of doing it on your own.
If you want to learn the subject, you MUST do such simple standard calculations on your own.
If you want to get calculations using regular hand calculator TI-83 or TI-84,
learn how to do it from this YouTube video-lesson
