WebP(X<2.201)=.975 P(X>2.201)=.025 df=11 Table of t values and right tail probabilities. Degrees of freedom are in the rst column (df). Right tail proba-bilities are in the rst row. For example for d.f. = 7 and a = .05 the critical t value for a two-tail test is 2.365 and for d.f. = 10 and a = .1 the critical t value for a one-tail test is 1.372. Web29 Apr 2024 · In most cases, you will use the highlighted column (α = .05). The critical value of t for your test is found where the row and column meet. Example: Finding the critical value of t in the t table. Using the t table, you find that for a two-tailed test with df = 29 and α = .05 the critical value of t is 2.045.

Web6 Jan 2016 · Because the curve is symmetric, there is 2.5% in each tail. Since the total area under the curve = 1, the cumulative probability of Z> +1.96 = 0/025. A "Z table" provides the area under the normal curve associated with values of z. The table below gives cumulative probabilities for various Z scores. Using the z-table WebTable 1 presents the bids and offers submitted by the peers for the hour t = 14.
