Question

A population has a mean

μ=163

and a standard deviation

σ=22.

Find the mean and standard deviation of the sampling distribution of sample means with sample size

n=50.

The mean is

μx=enter your response here,

and the standard deviation is

σx=enter your response here.

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
