How does Lean Six Sigma work? Wrap-up Lean Six Sigma is a process improvement methodology designed to eliminate problems, remove waste and inefficiency, and improve working conditions to provide a better response to customers’ needs. It combines the tools, methods and principles of Lean and Six...
Also note that Lean does not require parentheses when applying functions: we write D k here rather than D(k) (which in fact does not compile in Lean unless one puts a space between the D and the parentheses). This is slightly different from standard mathematical notation, but is not too...
, but rather “How many extra nines of safety does it add?”. As one final comparison between nines of safety and other standard risk measures, we give the following proposition regarding large deviations from the mean. Proposition 12 Let be a normally distributed random variable of standard...
Mathematically, Standard Deviation is calculated by taking the square root of the Variance. Variance measures the average squared difference between each Data Point and the Mean. While, Standard Deviation brings this measure back to the original units of the data, making it more interpretable. A ...
The way space bends back on itself would mean that we would see repeat images of the same part of the universe in different parts of the sky as the light traveled along the different paths of this complex loop. It would be like living in a cosmic hall of mirrors. All we'd need to ...
If there are 34 observations, how many degrees of freedom are there for the t-distribution (for a sample mean)? Does distribution add to cost and not value? In a particular chi-square goodness-of-fit test, there are six categories and 500 observations. Use the .01 significance level. a...
(b) What does this indicate about how accurately the mean summarizes the scores. (c) What will this do to the z-score for someone who is relatively far from the mean? W In a bell-shaped data set with mean 50, approximate...
Partial Differential Equations are the building bricks of a large part of models that are used to mathematically describe physics phenomenologies. Such models have been deeply investigated and often solved with the help of different numerical strategies. Stability and convergence of these strategies have...
I am going to tell you what nature behaves like. If you will simply admit that maybe she does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possibly avoid it, “But how can it be like that?” because you will get “...
What you learn from this is that between September and November, afterthe original OPERA result(what I call OPERA-1) was released publicly and the media frenzy began, OPERA personnel did what they should do: they made many studies of their work to see if they could find mis...
