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 using either statistical software or a t -table that … WebThis critical values calculator is designed to accept your p-value (willingness to accept an incorrect hypothesis) and degrees of freedom. The degrees of freedom for a t-distribution can be derived from the sample size - just subtract one. (degrees of freedom = sample size - 1). You can use this as a critical value calculator with sample size.
