Answer:

Last option

${\overline {x}}} \± \frac{2.58*s}{\sqrt{n}$

Step-by-step explanation:

${\overline {x}}$

If we extract a sample of size n from a normal population and we want to estimate the population mean then the confidence interval for the mean will be:

${\overline {x}}} \± Z_{\alpha/ 2}*\frac{s}{\sqrt{n}$

Where

Where ${\overline {x}}$ is an estimator for the mean μ.

n is the sample size and s is its standard deviation.

$\alpha$ is the level of significance

$\alpha$ = 1-Confidence Level

$\alpha= 1-0.99$

$\alpha = 0.01$

Then $Z_{\frac{\alpha}{2}} = Z_{\frac{0.01}{2}} = Z_{0.005}=2.58$

Then the 99% confidence interval for the population mean is

${\overline {x}}} \± \frac{2.58*s}{\sqrt{n}$
