Applications of the Normal Distribution. When dealing with applications using the normal distribution, standardized the random variable to a standard normal random variable. Draw a picture of the curve and shade in the interval of which you want to find the probability. The normal distribution underlies much of statistical theory, and many statistical tests require the errors, or the test statistic, represent a normal distribution. The test statistic's distribution cannot be assessed directly without resampling procedures, so the conventional approach has been to test the deviations from model predictions.

The more things you look at, the more youвЂ™ll find it. Go to a shoe shop and take a look at their stocks, if theyвЂ™ll let you, and you will find that there are a lot more shoes of adult size 4 - 8 than there are of adult size 10 - 12: the reason is all down to the normal distribution curve.

So, the area under the entire normal distribution curve must be 1 (equal to 100%). For example, if the mean (average) male height is 5'10" then there is a 50% chance that a randomly selected male will have a height that is below or exactly 5'10". This is because the area under the normal curve from the left hand side up to the mean consists... 14.11.2019В В· Normal Distribution - Real-World Problems Using z Values Now that you can calculate probabilities using a z table, it is time to use this knowledge to solve real-world problems.
