Question

to investigate whether or not sexism was present in the workplace, 48 male bank supervisors were each given a personnel file and asked to judge whether the person represented in this file should be recommended for promotion or whether the person's file should be held. The files were identical except that half of the files were labeled Male and the other half Female. The data is summarized below.

Promote No promotion Total
Male 21 3 24
Female 14 10 24
Total 35 13 48

Answer 1

There may be sexism present in this workplace.

One way to look at the data is to determine the percent of each sex that got promoted.

For the men, it was 21 out 24 or 87.5%.
For the women, it was 14 out of 24 or 58.3%.

That is more than a 29% difference. That doesn't prove that there is sexism, but it does raise more questions.
