Answer:
4.24
Explanation:
First you find the mean of the data set, which is 7. Then to find standard deviation you have to follow the formula which tells you to subtract the mean from each number under the square root : √(2 - 7)^2 + (9 - 7)^2 + (10 - 7)^2 + (4 - 7)^2 + (8 - 7)^2 + (4 - 7)^2 + (12 - 7). Once you solve the parenthesis you square it, once you square it the negatives won't matter. That will leave you with this : √(25 + 4 + 9 + 9 + 25). The formula tells you to find the sum of those numbers (which is 72) then subtract one from how many numbers there are, 5 - 1 = 4, and divide your sum by that number. So 72 / 4 = 18. Then you find the square root of 18 and that becomes your answer.

<h3>What is Troubleshooting?</h3>
This refers to the diagnostics that is run on a computer program or system in order to find the problem that is causing it to malfunction or misbehave.
Hence, we can see that based on the fact that several users on the second floor of your company's building are reporting that the network is down and go to the second floor to investigate and find that you are able to access the network, the troubleshooting step that you should take next is to Question User.

Using the knowledge of computational language in python it is possible to write a code that write (define) a public static method named countup, that takes one int argument and returns no value.
<h3>Writting the code:</h3>
<em>public class </em><em>Main</em>
<em>{</em>
<em>public static void main(</em><em>String</em><em>[] args) {</em>
<em>// testing the method </em><em>countDown </em><em>with values 5, 6, 1</em>
<em>countDown(5);</em>
<em>System.out.println();</em>
<em>countDown(6);</em>
<em>System.out.println();</em>
<em>countDown(2);</em>
<em>System.out.println();</em>
<em>}</em>
<em />
<em>public static void </em><em>countDown</em><em>(int num)</em>
<em>{</em>
<em>for (int i=1 ; i<=num ; i++) // for </em><em>loop </em><em>iterates from 1 to num</em>
<em>{</em>
<em>System.out.print(i+","); // prints num followed by comma ,</em>
<em>}</em>
<em>}</em>
<em>}</em>
