Since probability tables cannot be printed for every normal distribution, as there are an infinite variety of normal distributions, it is common practice to convert a normal to a standard normal (known as a z-score) and then use the standard normal table to find probabilities. See more 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 See more • Mathematics portal • 68–95–99.7 rule • t-distribution table See more Formatting / layout Z tables are typically composed as follows: • The label for rows contains the integer part and the first … See more A professor's exam scores are approximately distributed normally with mean 80 and standard deviation 5. Only a cumulative from mean table is available. • What is the probability that a student scores an 82 or less? P ( X ≤ 82 ) = P ( Z ≤ 82 − 80 5 ) = P ( Z ≤ … See more WebThe short answer is NO. Normal probability calculations are complex mathematical operations for which you need either a normal table, or a statistical software, or a hand …
