WebJul 11, 2024 · The critical values for any dataset can be calculated through the formula: Critical probability (p) = 1 – (Alpha / 2) Alpha = 1 – (the confidence level / 100) The answer to this formula can be either a z-score using the cumulative probability or a critical t-statistic. 1. … WebThe 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 ...
