The following are distances (in miles) traveled to the workplace by 6 employees of a certain university.13, 7, 34, 25, 14, 27Send data to calculatorFind the standard deviation of this sample of distances. Round your answer to two decimal places i need help with this math problem.

Respuesta :

The standard derivation of the sample (s) is:

[tex]s=\sqrt{\frac{\sum_{i\mathop{=}1}^n(x_i-x)^2}{(n-1)}}[/tex]

Where:

s = standard derivation of sample

n = number of data provided

xi = each of the values of the sample

x = the mean of xi

So, first, let's find the mean.

Given:

n = 6

The mean is:

[tex]\begin{gathered} x=\frac{\sum_{i\mathop{=}1}^nx_i}{n} \\ x=\frac{13+7+34+25+14+27}{6} \\ x=\frac{120}{6} \\ x=20 \end{gathered}[/tex]

And the standard derivation:

[tex]\begin{gathered} s=\sqrt{\frac{(13-20)^2+(7-20)^2+(34-20)^2+(25-20)^2+(14-20)^2+(27-20)^2}{6-1}} \\ s=\sqrt{\frac{(-7)^2+(-13)^2+(14)^2+(5)^2+(6)^2+(7)^2}{5}} \\ s=\sqrt{\frac{524}{5}} \\ s=10.24 \end{gathered}[/tex]

Answer: 10.24.
