An experiment was conducted to investigate the effect of two treatment T1, T2 on wheat growth. The experiment was carried out in two fields. 40 randomly selected plants were treated(20 with T1 and 20 withT2) in each field. The height of the mature plants were recorded as below (in cms). The interset is to answer the following questions.
1) Do the treatments appear to differ in their effect on the growth?
2) Is growth different in the fields?
3) Does the difference between the treatment differ between two fields?
