WebTo determine critical values, you need to know the distribution of your test statistic under the assumption that the null hypothesis holds. Critical values are then the points on the distribution which have the same probability as your test statistic, equal to the … WebTo find the critical points of a function y = f (x), just find x-values where the derivative f' (x) = 0 and also the x-values where f' (x) is not defined. These would give the x-values of the critical points and by substituting each of them in y = f (x) will give the y-values of the critical points. How to Find Critical Points On a Graph?
