Answer

# Brief Explanations: In the described study, the firm only collects data on existing variables (overtime hours and total output) without manipulating any factors. In an observational study, researchers observe and measure characteristics without attempting to influence the variables. In an experiment, there is manipulation of a factor to see its effect on another variable. Since no manipulation is done here, it's an observational study. # Answer: The research is an observational study
