If one of these plots yields 2.8 bushels, would that be a good or bad result? How do you know?

Use the data in "Wheat," (https://openstax.org/r/Chapter8 Data-Sets) which gives the yield of wheat (in bushels) produced over several equally sized plots. (These data were collected as part of an experiment reported in "The experimental error of field trials" (https://openstax.org/r/sets-059) by W.B. Mercer and A.D. Hall).
