How to solve the critical value
WebStep 1 Subtract the alpha value from 1. The alpha value is expressed as decimal less than one. As an example, say the alpha value is .03: Video of the Day 1 - 0.03 =0.97 Step 2 Divide the result from above by 2. All two-tailed tests must have this step.

WebNov 16, 2024 · The main point of this section is to work some examples finding critical points. So, let’s work some examples. Example 1 Determine all the critical points for the function. f (x) = 6x5 +33x4−30x3 +100 f ( x) = 6 x 5 + 33 x 4 − 30 x 3 + 100 Show Solution 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?
