The distribution of sample means is not always a normal distribution. Under what circumstances is the distribution of sample means not be normal? For a population with a mean of μ = 45 and a standard deviation of σ = 10, what is the standard error of the distribution of sample means for each of the following sample sizes? n = 4 scores n = 25 scores A population forms a normal distribution with a mean of μ = 55 and a standard deviation of σ = 12. For each of the following samples, compute the z-score for the sample mean. M = 58 for n = 4 scores M = 58 for n = 16 scores M = 58 for n = 36 scores
