The distribution of IQ scores of the population is normally distributed with a mean of 100 and a standard deviation of15 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 exactanswers as decimals.A single person with an IQ of 121: Z-score =Mean of a sample of 4 IQ's is 121: Z-score = 2.80Mean of a sample of 9 IQ's is 121: Z-score =1.40Mean of a sample of 25 IQ's is 121: Z-score =4.20Mean of a sample of 100 IQ's is 121: Z-score =Mean of a sample of 625 IQ's is 121: Z-score =7.0014.0035.00 A single person with an IQ of 106: Z-score =Mean of a sample of 4 IQ's is 106: Z-score =Mean of a sample of 9 IQ's is 106: Z-score =Mean of a sample of 25 IQ's is 106: Z-score =Mean of a sample of 100 IQ's is 106: Z-score =Mean of a sample of 625 IQ's is 106: Z-score =
