William Gosset (a.k.a. Student) did an experiment in which regular and kiln dried seeds were planted in adjacent plots in 11 fields. The yield (lbs/acre) for each plot was recorded at harvest. The data are available in the gosset data set.
a) Why was it important to plant seeds in adjacent plots in a variety of fields?
b) Do the data suggest that one method of preparing the seeds is better than the other?
