Find the percentage of values below a given z-score in a standard normal distribution.

STANDARD NORMAL DISTRIBUTION TABLE Entries represent Pr(Z ≤ z). The value of z to the first decimal is given in the left column. The second decimal is given in the top row.

Standard Normal Table Note: An entry in the table is the area under the curve to the left of z, P(Z ≤ z) = Φ(z) Z
