Left tailed t table
NettetThe critical value for conducting the left-tailed test H0 : μ = 3 versus HA : μ < 3 is the t -value, denoted -t( α, n - 1) , such that the probability to the left of it is α. It can be shown using either statistical software or a t -table that the critical value -t0.05,14 is -1.7613. That is, we would reject the null hypothesis H0 : μ = 3 ...

NettetStatistics - T-Distribution Table. Previous Page. Next Page. The critical values of t distribution are calculated according to the probabilities of two alpha values and the degrees of freedom. The Alpha (a) values 0.05 one tailed and 0.1 two tailed are the two columns to be compared with the degrees of freedom in the row of the table. NettetDepending on the test, choose one-tailed t distribution table or two-tailed t table below. Step 3: Look for the degree of freedom in the most left column. Also, look for the significance level α in the top row. Pick the value occurring on the intersection of mentioned row and column. In this case, the t critical value is 2.132.
