A consumer research company is interested in determining if a certain company's new refrigerator model is more efficient than the older model. Researchers decide to investigate the claim that the new model uses 10% less electricity than the older model for the same cooling load. To collect data, the company obtains 20 random refrigerators for each model. They are all placed in one building well separated from each other and are loaded with 50 bottles of water. The electricity usage is monitored for one month. How can the results be generalized?

Dax · Answer 1

The result should apply to any unit of the new model in comparison to any unit of the old model

Step-by-step explanation:

Since the refrigerators were randomly selected, whatsoever results comes out of the study can be generalized on both the new and old model that is if the new refrigerator cools faster, then it is safe to generalize for the basis of the study that new refrigerator cools faster that the old ones and vice versa.
