a. Define the term “Standard Error of M”

b. What happens to standard error of M as sample size increases?

c. If the standard error of M = 9 and we obtain a sample (n = 100) that is 12 points below the mean, would we consider this an extreme sample mean? (yes/no)
Explain.

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.
