Answer:

The top one is 135 cm^2

Step-by-step explanation:

To find the area, all you need to do is multiply the 3 different measurements. For the one in the top corner we need to multiply the length by the width by the height. The work is done below for you on that one.

A = l * w * h

A = 15 * 3 * 3

A = 135 cm^2

Determine mu subscript x overbarμx and sigma subscript x overbarσx from the given parameters of the population and the sample si

Alex

Answer:

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

And replacing we got:

$\mu_{\bar X}= 32$

$\sigma_{\bar X} = \frac{77}{\sqrt{23}} =10.06$

Step-by-step explanation:

Previous concepts

The central limit theorem states that "if we have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large".

Let X the random variable who represents the variable of interest, with the following properties:

$\mu =32,\sigma =77$

We select a sample of n=23 nails.

From the central limit theorem we can approximate that the distribution for the sample mean $\bar X$ is given by:

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

And replacing we got:

$\mu_{\bar X}= 77$

$\sigma_{\bar X} = \frac{77}{\sqrt{23}} =10.06$
