Chapter 14.5, Problem 15E

To determine

Find the standard error of the mean.

Answer to Problem 15E

  $0.7$

Explanation of Solution

Given information:

Given: $\sigma =13.5,N=375$

Calculation:

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

  $\begin{array}{l}{\sigma }_{\overline{X}}=\frac{Standarddeviation}{\sqrt{N}}\\ {\sigma }_{\overline{X}}=\frac{13.5}{\sqrt{375}}=0.7\end{array}$

Hence, the standard error is $0.7$ .
