Problem
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. Which data collection method is appropriate? Select only one answer choice. Select the correct answer below: The Company should obtain random samples of people who own each model and measure the electricity used over one month for each refrigerator. The company should obtain random samples of each model, place them in similar conditions, fill them with the same amount of water bottles, and monitor their electrical usage over one month. The company should get a random sample of the new model, place them all in similar conditions, fill them with the same number of water bottles, and monitor their electrical usage over one month. The company should obtain one new model and one old model, place them both in the same room, fill them with the same number of water bottles, and monitor their electrical usage over one month.
The response should include a reference list. Using one-inch margins, Times New Roman 12 pnt font, double-space and APA style of writing and citations.
