Question

A certain change in a process for manufacturing component parts is being considered. Samples are taken under both the existing and the new process so as to determine if the new process results in an improvement What are the populations of study

Answer 1

1) The total number of component parts in the existing process, and

2) The total number of component parts in the new process

Explanation:

A population is a group of items that are considered during an experimental or observational study.

In the study referred to in this question, the populations are:

1) The total number of component parts in the existing process, and

2) The total number of component parts in the new process

They are the populations because they are the objects of consideration in the study and it is from them that the samples needed for the observation are selected.
