Give some examples from your own business life of random processes that are likely to be normally distributed, and say how many sigmas you think the process should be at. In many of the real life situations that people encounter, there are random effects that influence them. This is not possible only once but rather throughout an interval or sequence of life. In some instances during holidays, we choose among the six of us who would be going to open our family business. We have agreed to be tossing a dice and the number on the face would be going no matter how many times that happens. Having a standard deviation that ranges at -1 to +1 from the mean, it means that 68% chances will end up with different characters. This would be 2 sigmas.

Explanation / Answer

Example for a real life sample which follows a normal distribution is

I woked in a TANG plant, let us discuss about packing 500 g pack

there is always a problem in filling between 492-508 and they treat it as 95% CI i.e 4 standard deviations

i.e two on either side

But when machine gives 2 standard deviations we become alert to maintain the process in control

Here standard devaition is the parameter set by us, to decide the level of sigma does the process follows

So, if we have more standard deviation we have chance of extending tolerances

The same happens when sudden break down happens or operator is not concerned abt (takes a holiday)

For the given tolerances, the sigma level breaks and reaches critical region of 95%

He has to given orienation of importance of sigma level
