Appendix C:Table for Cumulative Standard Normal Distribution
The following table gives values for the cumulative standard normal distribution function. The probability density function for the standard normal random variable, z, is:
The cumulative distribution function is given by:
The table has values for Φ(z) for nonnegative values for z (for the range 0 ≤ z ≤ 4.99). The values for negative values for z can be found by using the following equation because standard normal distribution is symmetrical:
We read values such as Φ(3.39) = 0.936505 = 0.9996505:
