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 ... WebRemark. Using the p-value method, you could choose any appropriate signs level she want; you are cannot limited to by α = 0.05.
