Standard Normal Table Note: An entry in the table is the area under the curve to the left of z, P(Z ≤ z) = Φ(z) Z 0.00 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09
The z-scores to the right of the mean are positive and the z-scores to the left of the mean are negative. If you look up the score in the z-table, you can tell what percentage of the population is above or below your score. The table below shows a z-score of 2.0 highlighted, showing .9772 (which converts to 97.72%).

Solution: The z score for the given data is, z= (85-70)/12=1.25. From the z score table, the fraction of the data within this score is 0.8944. This means 89.44 % of the students are within the test scores of 85 and hence the percentage of students who are above the test scores of 85 = (100-89.44)% = 10.56 %.
z-table. The table summarizes the standard normal distribution critical values and the corresponding (1-α). This z-score table contains the standard normal distribution critical values and the corresponding (1-α). Find the z-score you need here.
Oct 6, 2023 · The z-score consists of a whole number and decimal parts; For example, if your z-score is 1.24, the whole number part is 1, and the decimal part is 0.24; 2. Find the corresponding probability in the z-score table: Z-score tables are usually organized with the whole number part of the z-score in the leftmost column and the decimal part across ...
Standard Normal Distribution Tables STANDARD NORMAL DISTRIBUTION: Table Values Re resent AREA to the LEFT of the Z score. -3.9 -3.8 -3.6 -3.5
The standard deviation is 0.15m, so: 0.45m / 0.15m = 3 standard deviations. So to convert a value to a Standard Score ("z-score"): first subtract the mean, then divide by the Standard Deviation. And doing that is called "Standardizing": We can take any Normal Distribution and convert it to The Standard Normal Distribution.
