xz_007 [3.2K]

Answer:

\bar X \sim N(\mu , \frac{\sigma}{\sqrt{n}})

And replacing:

\mu_{\bar X}= 5

And the deviation:

\sigma_{\bar X}= \frac{0.283}{\sqrt{5}}= 0.126

And the distribution is given:

\bar X \sim N(\mu= 0.08, \sigma= 0.126)

Step-by-step explanation:

For this case we have the following info given :

\mu= 5. \sigma^2 =0.08

And the deviation would be \sigma = \sqrt{0.08}= 0.283

For this case we select a sample size of n = 5 and the distirbution for the sample mean would be:

\bar X \sim N(\mu , \frac{\sigma}{\sqrt{n}})

And replacing:

\mu_{\bar X}= 5

And the deviation:

\sigma_{\bar X}= \frac{0.283}{\sqrt{5}}= 0.126

And the distribution is given:

\bar X \sim N(\mu= 0.08, \sigma= 0.126)
