IQ scores are normally distributed with a mean of 95 and a standard deviation of 18
IQ scores are normally distributed with a mean of 95 and a standard
deviation of 18. 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.
If the sample size is n=49, find the mean and standard deviation of the distribution of sample means.
The mean of the distribution of sample means is?
The standard deviation of the distribution of sample means is?
