### Customer Question

Two Sample Test of Hypothesis

1.     Mary Jo is the Vice President of Nursing services at St. Luke's Memorial Hospital. Recently she noticed that in the job postings for nurses that those that are unionized seem to offer higher wages. She decided to investigate and gathered the following sample information.

Group     Mean Wage     Sample Std Deviation     Sample Size
Union         \$20.75                 \$2.25                        40
Nonunion \$19.80                  \$1.90                       ; 45

Would it be reasonable for her to conclude that union nurses earn more? Use the .02 significance level.

Dolly why are you asking? Is there a way to understand this class?
Expert:  Dolly replied 9 years ago.

You have to make your own brief notes as you go along. Your notes need to contain the equations with a written note about when that equation is used. I have your text and can offer you assistance. In my estimation, statistics is one of the more difficult subjects to understand in the business curriculum.
