The American Beef Growers Association is trying to promote the consumption of beef products. The organization performs numerous studies, the results of which are often used in advertising campaigns. One such study involved a quality perception test. Three grades of beef were involve: choice, standard, and economy. A random sample of people was provided pieces of choice-grade beefsteak and was asked to rate its quality on a scale of 1 to 100. A second sample of people was given pieces of standard-grade beefsteak, and the third sample was given pieces of economy-grade beefsteak, with instructions to rate the beef on the 100-point scale. The following data were obtained:
