3 days ago The standard normal distribution is a probability distribution, so the area under the curve between two points tells you the probability of variables taking on a range of values. The total area under the curve is 1 or 100%. Every z-score has an associated p-value that tells you the probability of all values below or above that z-score occuring. Thi...
