A computer network manager wants to test the reliability of some new and expensive fiber-optic Ethernet cables that the IT department just received. The IT department received 4 boxes containing 30 cables each. The manager does not have the time to test every cable in each box. The manager will choose one box at random and test 6 cables chosen randomly within that box. What is the population of interest?

the 120 cables delivered

the 4 boxes

the 6 cables chosen randomly for testing

the one box that was chosen at random from the 4 boxes

Solution

Given

A computer network manager wants to test the reliability of some new and expensive fiber-optic Ethernet cables that the IT department just received. The IT department received 4 boxes containing 30 cables each. The manager does not have the time to test every cable in each box. The manager will choose one box at random and test 6 cables chosen randomly within that box.

we have to tell that what is population of intersest

since

The population of interest is the population you are trying to draw an inference about from the collected data sets.

since here we tried to draw inference about 120 cables fro 4 boxes so

120 cables delivered from 4 boxes are population of interest.
