Chapter 14, Problem 29SGA

To determine

To find the standard error of the mean for each sample.

Answer to Problem 29SGA

  $0.16$

Explanation of Solution

Given:

  $\sigma =1.5,N=90$ .

Calculation:

Using the below formula to calculate the standard error of the mean for the given sample-

  $\begin{array}{l}{\sigma }_{\overline{X}}=\frac{\sigma }{\sqrt{N}}\\ {\sigma }_{\overline{X}}=\frac{1.5}{\sqrt{90}}\\ {\sigma }_{\overline{X}}\approx 0.16\end{array}$
