Question

If a sample is selected from a normal population with μ=200 and σ=20 and that sample has a mean of M = 205, for which of the following sample sizes would that sample be extreme and very unlikely to be obtained?

a. n = 100

b. n = 16

c. The three samples are equally likely to be obtained.

d. n = 36

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.
