Question

quality control finds on average that 0.038% of the items from a certain factory are defective one month 8000 items are checked

Answer 1

If the average of defective items is 0.038% then we will get 3 items being defective from 8000 items which are checked.

Given that the average of finding a defective item is 0.038%.

We are required to find the number if defective items that we will find from 8000 items.

Percentage is the number or ratio that is expressed in terms of 100. It is expressed as %.

Average of defective items=0.038%

Number of items checked=8000

Number of defective items that we will get=8000*0.038/100

=304.100

=3.04

Approximately 3 items.

Hence if the average of defective items is 0.038% then we will get 3 items being defective from 8000 items which are checked.
