Find critical value ti 84.

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.
