WebFeb 4, 2024 · The test statistic is calculated by the formula. z = ( x -bar - μ 0 )/ (σ/√ n) = (10.5 - 11)/ (0.6/√ 9) = -0.5/0.2 = -2.5. We now need to determine how likely this value of z is due to chance alone. By using a table of z -scores we see that the probability that z is less than or equal to -2.5 is 0.0062. Since this p-value is less than the ... 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 ...
