What proportion of yields does the normal distribution predict should fall below 4.56 ? Round to the nearest thousandth.

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).
