Quizplus · Accepted Answer

Tables of normal distribution probabilities are based on a standard normal distribution with a mean of 0 and a standard deviation of 1. Any normal distribution can be converted to a standard normal distribution using the formula z = (x - μ) / σ where z is the standard score, x is the raw score, μ is the mean, and σ is the standard deviation.
