The mean annual income for adult women in one city is $28,520 and the standard deviation of the incomes is $5600. The distributi

pshichka [43]

Answer:

$E(\bar{x}) = 28520$

Standard error of mean = 689

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = $28,520

Standard Deviation, σ = $5600

Mean of sampling distribution =

$E(\bar{x}) = \mu = 28520$

As per Central Limit Theorem, if the sample size is large enough, then the sampling distribution of the sample means follow approximately a normal distribution.

Sample size, n = 66

Since the sample size is large, we can use normal distribution for approximation.

Standard error of mean =

$\displaystyle\frac{\sigma}{\sqrt{n}} = \frac{5600}{\sqrt{66}} = 689.31 \approx 689$

Plz help Don’t know which one it is?

Answer:

First option $6^\frac{1}{6}$ is the correct answer.

Step-by-step explanation:

Let us consider each part, we have number 6 inside all the roots.

First we have to find cube root of 6.

$\sqrt[3]{6} =6^\frac{1}{3}$

Now we have to find square root of this value.

$\sqrt{6^\frac{1}{3} } =(6^\frac{1}{3} )^\frac{1}{2} =6^\frac{1}{6}$

So, first option $6^\frac{1}{6}$ is the correct answer.
