Suppose the population of IQ scores in the town or city where you live is bell-shaped, with a mean of 104 and a standard deviati

SVEN [57.7K]

Answer:

The mean of samples of 100 IQ scores taken out from this population will have a distribution with mean M=104 and standard deviation s=3.5.

Step-by-step explanation:

We know the population mean and standard deviation, that has a bell-shaped distribution:

$\mu=104\\\\\sigma=35$

The sampling distribution, the distribution of the mean of samples of size n out of this population, will have the same mean as the population mean.

$\mu_M=\mu=104$

The standard deviation will be related to the population standard deviation and the sample size as:

$\sigma_M=\frac{\sigma}{\sqrt{N}} =\frac{35}{\sqrt{100}}=3.5$

Then, the mean of samples of 100 IQ scores taken out from this population will have a distribution with mean M=104 and standard deviation s=3.5.

I don't understand calculus at all bruh :/. I figured out some of this but I don't know it the answer is 0 or 2. Whoever figures

Lady_Fox [76]

Answer:

-2

Step-by-step explanation:

This one you just plug in 32 because there is no denominator of 0.

So as x goes to 32, y would go to 2 because 5rt32 = 2

<u>EDIT</u>

My bad, i didn't see it as -32. the answer would be -2 though I believe bc

5rt-32 = -2
