The distribution of IQ scores of the population is normally distributed with a mean of 100 and a standard deviation 15 for a particular data value. Since the population is normally distributed all sampling distributions will also be normally distributed. Find the z-scores for each of the following. Make sure to pay attention to the distribution you should use. Write exa answers as decimals.

The distribution of IQ scores of the population is normally distributed with a mean of 100 and a standard deviation of
15 for a particular data value.
Since the population is normally distributed all sampling distributions will also be normally distributed.
Find the z-scores for each of the following. Make sure to pay attention to the distribution you should use. Write exact
answers as decimals.
A single person with an IQ of 121: Z-score =
Mean of a sample of 4 IQ's is 121: Z-score =
Mean of a sample of 9 IQ's is 121: Z-score =
Mean of a sample of 25 IQ's is 121: Z-score =
Mean of a sample of 100 IQ's is 121: Z-score =
Mean of a sample of 625 IQ's is 121: Z-score =
