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
Question : (a) Identify the model for comparing the wheat yield?
(b) Is there evidence at the 5% significance level that the yield of the new variety is higher?
ANSWER QUESTION (a) necessary.
