Hello, I assume that your SUPERIOR goal is to learn the subject and to learn on how to solve such problems ON YOUR OWN

rather than request the tutors make YOUR JOB.


If so, and if I guessed your superior goal correctly, then go to the Internet and find there &amp;nbsp;(free of charge) &amp;nbsp;online calculators

which will help you NOT ONLY compute what you need, but also will explain it to you all the relevant theory PROFESSIONALLY.


You may find them via the GOOGLE search engine by entering appropriate key words such as


    &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&quot;Find the range, variance, standard deviation and coefficient of variation online solver&quot;



Google will offer you tens of links.



For example, this one

http://statisticshelper.com/range-standard-deviation-and-variance-calculator


or this one

https://ncalculators.com/statistics/coefficient-of-variance-calculator.htm



It is easy to master these solvers, and when you learn on how to use them, you will feel yourself 
as a King of the statistical data processing.


If not as a King, &amp;nbsp;then as a Queen.



Good luck (!)
