Relevance and Uses of Standard Normal Distribution Formula Standard Distribution is broadly used in detecting the probabilities of score occurrence within normal distribution and which can be compared with the normal distribution points. This is a very useful tool that is frequently used in the Statisti...
The z score for a value of 1380 is 1.53. That means 1380 is 1.53 standard deviations from the mean of your distribution. Next, we can find the probability of this score using a z table.Use the standard normal distribution to find probabilityThe...
The standard normal distribution table is a compilation of areas from thestandard normal distribution, more commonly known as a bell curve, which provides the area of the region located under the bell curve and to the left of a givenz-score to represent probabilities of occurrence in a given ...
As a simple application, what portion of a normal distribution with a mean of 50 and a standard deviation of 10 is below 26? Applying the formula, we obtainZ = (26 - 50)/10 = -2.4.From Table 1, we can see that 0.0082 of the distribution is below -2.4. There is no need to ...
