Chapter 14.5, Problem 11E

To determine

Find the standard error of the mean.

Answer to Problem 11E

  $0.37$

Explanation of Solution

Given information:

Given: $\sigma =5.8,N=250$

Calculation:

Here, to find the standard error we will use the following formula:

  $\begin{array}{l}{\sigma }_{\overline{X}}=\frac{Standarddeviation}{\sqrt{N}}\\ {\sigma }_{\overline{X}}=\frac{5.8}{\sqrt{250}}=0.37\end{array}$

Hence, the standard error is $0.37$ .
