Question

Jennifer Jenson learns that the Newport Temp Agency has hired only 15 women among its last 40 new employees. She also learns that the pool of applicants is very large, with an equal number of qualified men and women. Find the probability that among 40 such applicants, the number of women is 15 or fewer. Based on the result, is there strong evidence to charge that the Newport Temp Agency is discriminating against women?

Solution

VerifiedStep 1

1 of 3The mean is the product of the sample size and probability $p$:

$\mu=np=40\times 0.5=20$

The standard deviation is the square root of the sample size, probability $p$ and $q(=1-p)$.

$\sigma=\sqrt{npq}=\sqrt{40\times 0.5\times (1-0.5)}\approx 3.162$
