Question

Q5: P ( Z ≤ 0.76 | Z ≥ -0.24) = ?

Given that the area is a probability defined from 0 to Z . Please show work on how to do the solution.

Answer 1

P(Z < 0.76 | Z > -0.24) = P(-0.24 < Z < 0.76) / P(Z > -0.24)

                                     = [P(Z < 0.76) - P(Z < -0.24)] / [1 - P(A < -0.24)]

                                     = (0.7764 - 0.4052) / (1 - 0.4052)

                                     = 0.6241
