# Calculation of Z-Statistic

The purpose of Team C's research is to determine why men receive higher salaries than women. Before researching the topic, team c will verify that women do indeed make less than men. According to the wages data set, women consist of only 3 of the top 25 salaries out of 100 samples. The mean women's salary is \$24,452 with a standard deviation of \$12,446, and the mean for the men's salary is \$36,493 with a standard deviation of \$18,448. Our hypothesis is that men receive higher salaries than women. This hypothesis can be stated numerically as follows:
One-tailed (right-tailed)
H0: µ &#8804; \$24,452
H1: µ > \$24,452
(Can you please tell me how to perform the Z Statistics Calculations
z = .x - &#956;0 =
&#416;/&#8730;n

Z equals x bar minus MuO divided by sigma divided by the square root of he sample size)

I think that Z= 24,452 - the hypothesized mean (&#956;0) divided by 12,446 (S.D.) divided by the square root of 100 (Sample Size). I just need you to fill in the hypothesized mean and perform the calculations.

I would really appreciate it.

Thank you
