Complete Question

A Six Sigma level is calculated by which of the following equations: Select one:

a. (Opportunities - Defects) / Opportunities x 100

b. (Opportunities + Defects) / Opportunities x 100

c. (Defects - Opportunities) / Defects x 100

d. (Defects + Opportunities) / Defects x 100

Answer:

a. (Opportunities - Defects) / Opportunities x 100

Explanation:

A Six Sigma level can be defined as statistical analysis that is used to access the quality of a product or service.

A Six Sigma level is a statistical procedure that involves the collection of data that is used to detect any form of defect in a process, product or service such that the highest or maximum level or quality is obtained from such a process, product or service.

The Six sigma level is determined or calculated by subtracting the total number of defects from the total number of opportunities and then dividing by the total number of opportunities, and finally multiplying the result by 100.

This is can be represented mathematically as:

Option a. (Opportunities - Defects) / Opportunities x 100

Where:

a) Opportunities can be defined as any aspect in a process, product of service where a defect can occur.

b) Defects can be defined as the non conformity of a process, product or service to a quality standard.

A defect can also be defined as when a products falls below the acceptable standard by a customer.
