WebOct 10, 2024 · For example, if the confidence level is 85%, here is the equation to determine the alpha value: a = 1 - (85/100) = 0.15. 2. Calculate critical probability. The next step is finding the critical probability, or critical value, using the alpha value that was calculated in the first equation. In this equation, "p * " represents the critical ... WebFor this test, the rejection region of 0.05 would be entirely within the upper tail. The critical z ‐value for a probability of 0.05 in the upper tail is 1.65. (Remember that Table 2 in "Statistics Tables" gives areas of the curve below z; so you look up the z ‐value for a probability of 0.95.)
