In … WebAug 8, 2024 · Answer: 0.0668 Use the z - table to find where the row for 1.5 intersects with the column for 0.00, which is 0.9332. Because the z - table gives you only "less than" probabilities, subtract P ( Z < 1.5) from 1 (remember that the total probability for the normal distribution is 1.00, or 100%): P ( Z ≥ 1.5) = 1 – P ( Z < 1.5) = 1 – 0.9332 = 0.0668
WebThe probability is the area below the Normal distribution's curve. For a score of z = 3.16, the area under the Normal distribution from − ∞ σ to 3.16 σ is ≈ 1 (this is the probability). Note this an an estimate. There does exist a very small amount of area (again, synonymous with probability) above 3.16 σ.
