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.
