Answer:

When seeking to determine the number of shirts made by employees subjected to noise with and without the use of headphones, the dependent variable is the number of shirts made by the employee.

Explanation:

In a study or research, the dependent variable is the result of the intervention on the independent variable, which can be modified. In the case presented, the dependent variable is the quantity of shirts made by the employees, the number of which is measured at the end of the study.

It is expected that those employees who block the noise using headphones produce a greater number of shirts than those exposed totally or partially to noise.

For the other options:

  • <u><em>The type of music the employees listen to while they work</em></u><em>.  Does not represent dependent or independent variable.</em>
  • <u><em>The amount of training employees need</em></u><em>. It is not the variable being studied.</em>
