= IQ scores are normally distributed with a mean of 95 and a standard deviation of 16. Assume that many samples of size n are taken from a large population of people and the mean IQ score is computed for each sample. a. If the sample size is n=64, find the mean and standard deviation of the distribution of sample means.. The mean of the distribution of sample means is 95. The standard deviation of the distribution of sample means is 2. (Type an integer or decimal rounded to the nearest tenth as needed.) b. If the sample size is n= 100, find the mean and standard deviation of the distribution of sample means. The mean of the distribution of sample means is 1.6 = IQ scores are normally distributed with a mean of 95 and a standard deviation of 16.
