WebThe cumulative distribution function of a real-valued random variable is the function given by [2] : p. 77. where the right-hand side represents the probability that the random variable takes on a value less than or equal to . The probability that lies in the semi-closed interval , where , is therefore [2] : p. 84. WebChoose Inverse cumulative probability. In Mean, enter 1000. In Standard deviation, enter 300. In Input constant, enter 0.025. Click OK. The time by which 2.5% of the heating elements are expected to have failed is the inverse CDF of 0.025 or 412 hours. Repeat step 2, but enter 0.975 instead of 0.025. Click OK.

"WebDec 12, 2004 · To find z such that φ (z)= 0.25, you are looking for a z such that the area under the Normal curve to the left of z is 0.25. By symmetry, this is the same as area to the right of -z. Since your table starts with φ (0)= 0.5 up to φ (infinity)= 1, it is already including the left half. You need to find z such that Φ (z)= 1- 0.25= 0.75. " - Cumulative table phi
