Question

Consider the following set of data:

Men (1) Women (2)

Sample Size 100 80

Mean $12,850 $13,000

Standard Deviation $345 $500

To determine if the Men have a lower mean salary than the Women, we would test the following hypothesis

A) H0: μ1 < μ2, Ha: μ1 ≥ μ2

B) H0: μ1 = μ2, Ha: μ1 ≠ μ2

C) H0: μ1 ≥ μ2, Ha: μ1 < μ2

D) H0: μ1 ≤ μ2, Ha: μ1 > μ2

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.
