Suppose that a process is currently operating at a 3.5-sigma quality level, and it is planned to use improvement projects to move this process to a 6-sigma level? What project improvement rate would be necessary to achieve that new performance in 2 years?

Step-by-step explanation:

The following  formula is used to compute the Proportion of error-free units given the sigma level in Excel.

 The proportion of error-free units = NORMSDIST(Sigma Level - 1.5)

Suppose that a process is currently operating at a 3.5-sigma quality level.

The proportion of error-free units for this process is

                           NORMSDIST(3.5 - 1.5) = 0.977250

Therefore, the rejection rate is equal to

or 22750 PPM.

Now, consider a 6-sigma level process.

The proportion of error-free units equals

                     NORMSDIST(6.0 - 1.5) = 0.9999966

and the rejection rate is

Hence, reduction is PPM required per year , that is

reduction per year

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

the equivalent expression are always the hardest ones but you look at the gcf also
