In order to compare a new variety of wheat with a standard, an experiment is used with six plots receiving the new variety and ten plots receiving the standard. The yields (t/ha) are as follows: New variety: 2.6 2.1 2.5 2.4 1.9 2.3 Standard variety: 1.7 2.1 2.0 1.8 2.3 1.6 2.0 2.1 2.2 1.9 a) Identify the model for comparing the w
