The normal distribution is important in statistics and is often used in the natural and social sciences to represent real-valued random variables whose distributions are unknown.

Webb30 aug. 2024 · Suppose we would like to find the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1. Then we will subtract the smaller value from the larger value: 0.8413 – 0.6554 = 0.1859. Thus, the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1 is approximately 0.1859. Webb17 mars 2024 · To determine the probability that X is less than or equal to 5 we need to find the z -score for 5 in the normal distribution that we are using. Thus z = (5 – 10)/2.236 = -2.236. By consulting a table of z -scores we see that the probability that z is less than or equal to -2.236 is 1.267%.
