C) P(0 ≤ Z ≤ z)
D) P(Z ≥ -z)
E) P(z ≤ Z ≤ 0)

Question

Given that Z is a standard normal random variable, the area to the left of a value z is expressed as:A)  P(Z ≥ z)B)  P(Z ≤ z)C)  P(0 ≤ Z ≤ z)D)  P(Z ≥ -z)E)  P(z ≤ Z ≤ 0)

Jonathan Flowers · Accepted Answer

Final Answer : B, Explanation :  The area to the left of a value z corresponds to the cumulative probability up to z, which is expressed as P(Z ≤ z) for a standard normal distribution.
