In theory 69.1% scored less than you did (but with real data the percentage may be different)A Practical Example: Your company packages sugar in 1 kg bags.When you weigh a sample of bags you get these results:1007g, 1032g, 1002g, 983g, 1004g, ... (a hundred measurements) Mean =...
The probability density function for the normal distribution is given by: In the formula, μ (mu) is the population mean, σ (sigma) is the population standard deviation, and π (pi) is a mathematical constant approximately equal to 3.14159. The PDF shows that the normal distribution is ...
Purpose The purpose of this paper is to propose an approach for studying the Six Sigma metrics when the underlying distribution is lognormal. Design/methodology/approach The Six Sigma metrics are commonly available for normal processes that are run in the long run. However, there are situations ...
An Industry Example of the Normal Distribution A Six Sigma Green Belt wanted to know whether his data fulfilled the assumption of normality as required by the 2-sample t-test he wanted to do. Below are two probability plots for his two sets of data. Notice that one can be considered nor...
X represents the raw value of the measurement of interest. Mu and sigma represent the parameters for the population from which the observation was drawn. After you standardize your data, you can place them within the standard normal distribution. In this manner, standardization allows you to compa...

I'm generating a random normal distribution and i don't control the mu and sigma (i didn't wrote the script). Is there any way to change the mu and sigma and still keep the same ratio between the numbers in the vector? Or if you prefer i can ...
percentage has more? Definition. The standard normal distribution is the nor- mal distribution N(0, 1) with mean 0 and standard deviation 1. If a variable x has any normal distribution N(µ, σ) with mean µ and standard deviation σ, then the standardized vari- able z = x −...
Answer to: Normal distribution has mean mu = 250 and standard deviation sigma = 20. Find the 70% percentile for this distribution. By signing up,...
