WebIn order to find the probability that a z value is between 1.12 and 1.15, we determine the difference of the two probabilities. Thus, to calculate the probability that a z value is between 1.12 and 1.5, we find the difference: .9332 - .8686 = .0646. We now know that about 6.46% of the entire bell curve is between z = 1.12 and 1.5.
