In short, just subtract the values in this table above from 1. So for a z-score of -2, with a p-value of 0.5, that gives (1- 0.9798) = 0.0202 You will get a negative z-score when x x is less than μ μ in the …

Dec 14, 2017 · I understand where he got both the critical value and p-value from, I just don't understand why he's using the negative Z-score table. Is it because of the significance level of 5%?
