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](https://tex.z-dn.net/?f=%5Cmu%3D104%5C%5C%5C%5C%5Csigma%3D35)
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](https://tex.z-dn.net/?f=%5Cmu_M%3D%5Cmu%3D104)
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](https://tex.z-dn.net/?f=%5Csigma_M%3D%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7BN%7D%7D%20%3D%5Cfrac%7B35%7D%7B%5Csqrt%7B100%7D%7D%3D3.5)
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.
