(b) Define the term ‘process’. Give an example of process.
·         Explanation of two causes of variation.
·         Definition of a process and example of a process.
Answer:
Explanation of two causes of variation.
Variation can be defined as any deviation from the specified requirements. It can be either positive or negative.

(b) Calculate the standard deviation of the following data, which represents the number of defective products by a machine: 4, 2, 5, 8 and 6
·         Meaning of Standard Deviation
·         Calculation of Standard Deviation with steps
Answer:
Meaning of Standard Deviation:
Standard deviation is the root of sum of the squares of deviations divided by the total number of values given in the dataset. Standard deviation shows the degree of variation from mean or value expected. A low standard deviation suggests that points in data are closer to mean, and higher

Qus:5 Define the terms: ‘process capability’ and ‘process stability’. Explain Cp index and Cpk index.
·         Definition of ‘process capability’ and ‘process stability’
·         Explanation of Cp Index and Cpk Index

Answer:

Definition of ‘process capability’ and ‘process stability’

Process capability:

Process capability is defined as the capability of a process which is able to achieve the objective for which it exists within the constraints or the limits. In other words, it is defined as how likely a product is going to meet its predesigned specifications. These objectives and specifications are

iv) Acceptance Sampling
Meaning of:
·         i) Hypothesis testing
·         ii) Control chart
·         iii) Experimental design
·         iv) Acceptance Sampling

Answer:

i) Hypothesis testing:

Hypothesis testing is define as a process of resolving problems or deriving information from the given data in order to conduct crucial business decisions.
