Standard Normal Distribution Table (Right-Tail Probabilities)
In statistics, a standard normal table, also called the unit normal table or Z table, is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution. It is used to find the probability that a statistic is observed below, above, or between values on the standard normal distribution, and … See more Formatting / layout Z tables are typically composed as follows: • The label for rows contains the integer part and the first decimal place of Z. • The label for columns … See more • Mathematics portal • 68–95–99.7 rule • t-distribution table See more A professor's exam scores are approximately distributed normally with mean 80 and standard deviation 5.
