Why sigma is used in 6 sigma?
sigma represents standard deviation. In a normal distribution, +/- 1 sigma from the mean, for instance, corresponds to approximately 67% of the area under the normal distribution. +/- 2 sigma corrresponds to 95% of the area and +/- 3 sigma from the mean corresponds to 99% of the area under a normal distribution. The area that is covered under +/- six sigma from the mean corresponds to nearly 100% -- that is, the part of the area NOT under that +/- 6 sigma is in the 10^-15 range or 1/1,000,000,000,000,000. The six sigma name borrows from this to suggest that the method gives this degree of certainty: that in 999,999,999,999,999 in 1,000,000,000,000,000 cases the result will be predictable. It does nothing, however, to explain how an agricultural process management methodology applies to other fields.
How do you get the experimental value of a rectangle?
A rectangle has no value - experimental or otherwise. Its area has a value, its perimeter, its aspect have values.
How do you work out the value of a triangle?
A triangle does not have any particular value. There are the magnitudes of its size, its angles, its area, its perimeter etc, but no single VALUE.
What is the formula for finding percentage error in area of a circle?
It is 100*(Measured Value/True Value - 1)
Can a shape have the same area but not perimeter?
Most shapes have different perimeter than area, as far as value.
What z value corresponds to 17 percent of the data between the mean and the z value?
I believe your question is to find a range going from the mean to a z-value on the standard normal distribution that corresponds to 17% of the area. A normal distribution goes from values of minus infinity to positive infinity. A standard normal distribution has a mean of 0 and an standard deviation of 1. It is usually best if you draw a diagram, in this case a bell shape curve with mean = 0. The area to the left of the mean is 50% of the total area. We find a z value that corresponds to 67% (50% + 17%) of the area to the left of this value. This can be done either with a lookup table or a spreadsheet program. I prefer excel, +norminv(0.67) = 0.44. The problem could also be worded to find the area going from a z-value to the mean. In this case, we must find a z-value that corrsponds to 33% (50-17). Using Excel, I calculate +norminv(0.33) = -0.44.
The area to the left of z is 0.9976 What z-score corresponds to this area?
2.82
What is estimated value of z such that an area of 15 lies to the right of z?
There cannot be such a value since the total area, being a probability, is 1.
What ZIP Code corresponds to area code 202?
There are 300+ Zip Codes in area code 202, which is Washington, D.C.
What is the z score of 0.0011 that corresponds to the area under the standard normal curve?
3.06
A vertical line is drawn through a normal distribution at z equals plus 0 25 The line separates the distribution into two sections and the smaller section corresponds to of the whole distribution?
At Z = 0.25, the area (larger) to the left of the line is 0.5987. The smaller area to the right of the line is 1 - 0.5987 = 0.4013. Therefore, the smaller section corresponds to 40.13% of the area.
How three eighths in measurements?
It is three units out of every eight. Its value will depend on what is being measured: area, length, mass, etc and the units being used.
What modern area or country is ancient Thrace?
Ancient Thrace corresponds to an area that today would cover Southern Bulgaria, North Eastern Greece and European Turkey.
What does wild counterpart mean?
Counterpart-A person or thing holding a position or performing a function that corresponds to that of another person or thing in a different area.
What is the Spanish word for the area of north of Baja California?
"Alta California". Which nowadays corresponds to the U.S. state of California.
Why is it important to calculate the area under the normal curve where most competitors operate?
I will try to answer your question, although I am unclear about "where most competitors operate." The area under the normal curve from beginning to end (minus infinity to positive infinity) equals 1. The area from minus infinity to the median (also the mean) is always 0.5, which corresponds to a 50% probabability. If I want to know the probability of a value of x or less occurring, this would the area from negative infinity to x.
