IQ scores are normally distributed with a mean of 100 and a standard deviation of 18. Assume that many samples of sizes n Are taken from a large population of people and the mean IQ score is computed for each sample. If the sample size is n = 49, Find the mean and standard deviation of the distribution of sample means. The standard deviation of the distribution of sample mean is? (type in integer or decimal rounded to the nearest 10th as needed)
