Standard Normal Cumulative Probability Table Cumulative probabilities for NEGATIVE z-values are shown in the following table:
t DISTRIBUTION TABLE Entries provide the solution to Pr(t > t p) = p where t has a t distribution with the indicated degrees of freedom.

As shown in the illustration below, the values inside this table are critical values of the Chi-square distribution with the corresponding degrees of freedom. To determine the value from a Chi-square distribution (with a specific degree of freedom) which has a given area above it, go to the given area column and the desired degree of freedom row.
Confidence Interval Critical Values, zα/2 Level of Confidence Critical Value, z α/2 0.90 or 90% 1.645 0.95 or 95% 0.10 1.96 0.98 or 98% 2.33- 0.99 or 99%- 2.575 Hypothesis Testing Critical Values
Table entry Table entry for z is the area under the standard normal curve to the left of z. Standard Normal Probabilities z z.00 –3.4 –3.3 –3.2 –3.1 –3.0 –2.9 –2.8 –2.7 –2.6 –2.5 –2.4 –2.3 –2.2 –2.1 –2.0 –1.9 –1.8 –1.7 –1.6 –1.5 –1.4
Z is the standard normal random variable. The table value for Z is the value of the cumulative normal distribution. For example, the value for 1.96 is P(Z<1.96) = .9750. Find the p-value using the standard normal table.
The standard normal tables gives the areas under the normal curve to the left of the z‐value (see picture at the right). For z < ‐3.90, the areas are 0.0000 to four decimal places.
