WebFeb 16, 2024 · To find the area to the right of a positive z-score, begin by reading off the area in the standard normal distribution table. Since the total area under the bell curve is 1 (as a decimal value which is equivalent to 100%), we subtract the area from the table from 1. For example, the area to the left of z = 1.09 is given in the table as .8621. WebBelow we see a normal distribution.

WebJul 18, 2024 · A normal distribution can approximate X and has a mean equal to 64 inches (about 5ft 4in), and a standard deviation equal to 2.5 inches ( \mu μ =64 in, \sigma σ =2.5 in). X \sim N (\mu,\sigma) X ∼ N (μ, σ) X. X X is the height of adult women in the United States. μ. \mu μ is the mean height and is equal to 64 inches. σ.

WebThe grade is 65. Well first, you must see how far away the grade, 65 is from the mean. So 65 will be negative because its less than the mean. 65-81 is -16. Divide that by the standard deviation, which is 6.3. So -16 divided by 6.3 is -2.54, which is the z score or "the standard deviation away from the mean.
