Practice calculating p-values

In the original dataset, 87.5% of the men were promoted and 58.3% of the women were promoted.

Consider a situation where there are 24 men, 24 women, and 35 people are still promoted. But in this new scenario, 75% of the men are promoted and 70.8% of the women are promoted. Does the difference in promotion rates still appear to be statistically significant? That is, could this difference in promotion rates have come from random chance?

You'll analyze these new data, contained in disc_new, using the same permutation algorithm from before.

The disc_perm and disc_perm_new datasets are available in your workspace.
