   Suppose P(z ≥ z₁) = 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
