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.

For the other options:
- <u><em>The amount of noise</em></u><em>. This can modified by the use or not of headphones and is the independent variable, subject to modification.</em>
- <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>
