Question

check here for instructional material to complete this problem. evaluate the formula $e = z^{*}left(\frac{sigma}{sqrt{n}}
ight)$, where $z^{*}=2.576$, $sigma = 32.67$, and $n = 45$. $e=square$ (round to three decimal places as needed.)

Explanation:

Step1: Calculate square - root of n

$\sqrt{n}=\sqrt{45}\approx6.708$

Step2: Calculate $\frac{\sigma}{\sqrt{n}}$

$\frac{\sigma}{\sqrt{n}}=\frac{32.67}{6.708}\approx4.870$

Step3: Calculate E

$E = z^{*}(\frac{\sigma}{\sqrt{n}})=2.576\times4.870\approx12.545$

Answer:

$12.545$
