Question

A manager wanted to test whether the amount of noise in a clothing factory affected how

much work employees accomplished. Three groups of employees were tested every day
over a 5-day period. All three groups did the same type of work, they were all equally trained
to do the work, they used the same equipment, and they were tested the same time of day.
Group one was given headphones that blocked out all of the outside noise. Group two was
given headphones that blocked out some of the noise. Group three was not given anything
to block out the noise. The number of shirts made by the employees in one hour was
determined.
Which problem is being tested in this experiment?
How long does it take to make a certain brand of clothing?
O Which employees need more training?
O Does the amount of noise affect how much work employees do?
O Are headphones unsafe in the factory?

Answer 1

The problem that is being tested is Does the amount of noise affect how much work employees do?

Step-by-step explanation:

When a manager wanted to test whether the amount of noise in a clothing factory affected how much work employees accomplished, he performs an experiment modifying the amount of noise that employees endure through the use of headphones.

What the manager wants to know for sure is how much the amount of noise in the factory affects the productivity of the employees, which is expressed in the amount of shirts they can make exposed or not to the noise.

Noise reduction with the use of headphones would be expected to improve employee productivity.

The other options do not really identify the study problem, since the time it takes to make a certain brand of clothing, employee training or safety in the use of headphones in the factory is not being investigated.
