WebThere is no rule saying a function has to have ANY critical points. For example, f (x)= 3x+7 has no critical points. Your particular function has no REAL critical points. Most likely, that is what an introductory calculus course would be asking about, so you would most likely be expected to say it had no real critical points. WebCritical F values If we want to obtain the F value for a certain probability and ndf and ddf, we can use the finv() function. Suppose that we want to obtain the F value for a probability of 0.05 (5%), and ndf = 2 and ddf = 27, and the F-value for a probability of 0.01 (1%) and ndf = 1 and df = 26. We can use the following data step.

Say you have two groups, A and B, and you want to run a 2-sample t-test on them, with the alternative hypothesis being: Ha: µ.a ≠ µ.b. You will get some test statistic, call it t, and some p-value, call it p1. If you then run an ANOVA on these two groups, you will get an test statistic, f ... WebThe shaded area represents the probability of observing an F-value that is at least as large as the F-value our study obtained. F-values fall within this shaded region about 3.1% of the time when the null hypothesis is true. This probability is low enough to reject the null hypothesis using the common significance level of 0.05. We can conclude ... fedway
