After being rejected for employment, Kim Kelly learns that the Bellevue Credit Company has hired only three women among the last 16 new employees. She also learns that the pool of applicants is very large, with an approximately equal number of qualified men as qualified women.
Help her address the charge of gender discrimination by finding the probability of getting three or fewer women when 16 people are hired, assuming that there is no discrimination based on gender.
P(at most three) =
Because this is a serious claim, we will use a stricter cutoff value for unusual events. We will use 0.5% as the cutoff value (1 in 200 chance of happening by chance). With this in mind, does the resulting probability really support such a charge?
I'm a little confused with this exersise ; I used .5% as a probability , 16 as n , and 3 as x using binomial cumulative distribution , but I'm still missing something ( I believe it's the probability!). Can someone help me? thanks in advance!
