In the Traditional Method, you are comparing POINTS (the Test Statistic and the Critical Value); in the P-Value Method, you are comparing AREAS (the P-Value and α (alpha)). 9. If the P-Value is less than α (alpha), reject H 0 ("If P is low, H 0 must go"). 10. The Critical Value (point) sets the boundary for α (area).This is the critical value. Compare the absolute value of each residual value in [L3] to 7.64. If the absolute value is greater than 7.64, then the (x, y) corresponding point is an outlier. In this case, none of the points is an outlier.

May 13, 2019 · Using the TI-84 to find a critical value for a confidence interval for the mean when sigma is unknown. Critical Points. A critical point is an interior point in the domain of a function at which f ' ( x) = 0 or f ' does not exist. So the only possible candidates for the x -coordinate of an extreme point are the critical points and the endpoints. Finding the Extreme Values Using Calculus Techniques. Suppose a researcher is conduct a two-tailed hypothesis test using α = .05. What is the z-critical value that corresponds to this alpha level? To find this critical value, we can use the formula 1 – α/2. In this case, we will use 1 – .05/2 = .975 for the probability: The answer is z = 1.96. Example 3: Z-Critical Value for Cut-Off Scores Critical value (z*) for a given confidence level. If we want to be 95% confident, we need to build a confidence interval that extends about 2 standard errors above and below our estimate. More precisely, it's actually 1.96 standard errors.
