Final answer:
The purpose of the experiment is 3) to determine if the new coffee brand has no effect on worker productivity.
Step-by-step explanation:
The purpose of the experiment is to determine if the new coffee brand, Meeconsins Extra Calcine, has an effect on worker productivity. The manager of Acme Widget Company wants to see if changing the coffee brand in the break room will increase or decrease the number of widgets produced by each worker.
To determine the effect of the new coffee brand, the manager records the number of widgets produced by each worker on a Tuesday both before and after the coffee brand change. By comparing the productivity levels before and after the change, the manager can analyze if the new coffee brand has any impact on worker productivity.
The objective of the experiment is not specifically to increase or decrease worker productivity, but rather to determine if the new coffee brand has any effect on productivity. Therefore, the purpose of the experiment is to determine if the new coffee brand has no effect on worker productivity.
