    Suppose P(zz1) = 0.84, and z is normally distributed with a mean of 0 and variance of 1. What then is the corresponding value of z1?


    1. FALSE: Z1 ≤ 0,11
    2. FALSE: Z1≤ 1,96
    3. FALSE: Z1 = 0,96
    4. TRUE: Z1 = -1

    1. Z1 ≤ 0,11: Incorrect
    2. Z1≤ 1,96: Incorrect
    3. Z1 = 0.96: Incorrect
    4. Z1 = -1: Correct
