For the following experiment, indicate whether it was single-blind, double-blind, or not blinded at all. Explain your reasoning. Makers of a new frozen entree arranged for it to be served to randomly selected customers at a restaurant in place of the equivalent entree ordinarily prepared in the kitchen. After their meal, the customers were asked about the quality of the food. Choose the correct answer below. A. The experiment was double-blind because neither the customers nor the kitchen staff knew which treatment the customers received. B. The experiment was single-blind because the customers receiving the frozen entree did not know which treatment they were receiving, but the customers receiving the ordinary entree knew. C. The experiment was double-blind because neither group of customers knew which treatment they were receiving. D. The experiment was not blinded at all because both the customers and the kitchen staff knew which treatment the customers received. E. The experiment was single-blind because the customers did not know which treatments they were receiving, but the kitchen staff knew.

Based on the information given, it should be noted that the correct option is E. The experiment was single-blind because the customers did not know which treatments they were receiving, but the kitchen staff knew.

In conclusion, this shows a single-blind experiment.

E. The experiment was single-blind because the customers did not know which treatments they were receiving, but the kitchen staff knew.

Step-by-step explanation:

Blinding is a process in experimentation that aims to reduce observational and other forms of biases. For the experiment to be very effective, the kitchen staffs have to know since they would assist in making the normal entree and also help in serving the customers who are completely oblivious to the experiment. This is a case of single blindness as only the customers are technically unaware of the experiment.
