WebThe normal table provides probabilities from zero to the value Z 1. For this problem the question can be written as: P(X ≥ 65) = P(Z ≥ Z 1), which is the area in the tail. To find this area the formula would be 0.5 – P(X ≤ 65). One half of the probability is above the mean value because this is a symmetrical distribution. WebThe Standard Normal Distribution Table. The standard normal distribution table provides the probability that a normally distributed random variable Z, with mean equal to 0 and variance equal to 1, is less than or equal to z. It does this for positive values of z only (i.e., z-values on the right-hand side of the mean).

WebJul 24, 2016 · The table in the frame below shows the probabilities for the standard normal distribution. Examine the table and note that a "Z" score of 0.0 lists a probability of 0.50 or 50%, and a "Z" score of 1, meaning one standard deviation above the mean, lists a probability of 0.8413 or 84%. WebAug 8, 2024 · Because the z - table gives you only "less than" probabilities, subtract P ( Z < 1.5) from 1 (remember that the total probability for the normal distribution is 1.00, or 100%): P ( Z ≥ 1.5) = 1 – P ( Z < 1.5) = 1 – 0.9332 = 0.0668 …

WebStep 2: Look up the area under the standard normal distribution curve between the two z-scores in the standard normal table. The table gives the probabilities associated with each z-score. From the standard normal table, we find that the area to the left of z = -1 is 0.1587 and the area to the left of z = 1 is 0.8413.
