A restaurant chain, "Gourmet Grills," plans to expand its menu offerings and optimize its customer service experience. The management needs to analyze customer preferences and operational efficiency to make informed decisions. Which question would be an appropriate statistical question?

A statistical question anticipates variability in data and is answered by collecting or analyzing many observations. Customers’ dinner wait times differ from one visit to another, so finding the average over six months requires data from multiple visits. Therefore, “What is customers’ average wait time for dinner over the past six months?” is appropriate; the other choices ask for fixed facts or a specific schedule or price.
