Determine the upper-tail critical value
WebMay 27, 2024 · The critical value for the F-Test is defined as follows: F Critical Value = the value found in the F-distribution table with n1-1 and n2-1 degrees of freedom and a significance level of α. Suppose the sample variance for sample 1 is 30.5 and the sample variance for sample 2 is 20.5. This means that our test statistic is 30.5 / 20.5 = 1.487.

WebSep 24, 2024 · A two-tailed test has two critical values, one on each side of the distribution, which is often assumed to be symmetrical (e.g. Gaussian and Student-t distributions.). … WebNov 6, 2024 · Using the table of critical values for upper tailed tests, we can approximate the p-value. If we select α=0.025, the critical value is 1.96, and we still reject H 0 because 2.38 > 1.960. If we select α=0.010 the critical …
WebFor an upper-tail test, the p-value is the area under the curve of the t-distribution (with n−1 degrees of freedom) to the right of the observed t-statistic. For a lower-tail test, the p-value is the area under the curve of the t-distribution (with n−1 degrees of freedom) to the left of the observed t-statistic. WebThe critical value for conducting the right-tailed test H0 : μ = 3 versus HA : μ > 3 is the t -value, denoted t α, n - 1, such that the probability to the right of it is α. It can be shown …
