Computing p z
WebYou can also easily work in the other direction, and determine what a is given P(Z ≤ a) EX: Find a for P(Z ≤ a) = .6026, .9750, .3446 To solve: for p ≥ .5, find the probability value in Table I, and report the corresponding value for Z. For p < .5, compute 1 - p, find the corresponding Z value, and report the negative of that value, i.e. -Z. 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.
