1. [R] The yield of a chemical process is being studied. The two factors of interest are temperature and pressure. There levels of each factor were selected but only nine runs can be made in one day. The data are below:

Temp\Pressure	250	260	270
Low	86.3, 86.1	84, 85.2	85.8, 87.3
Medium	88.5, 89.4	87.3, 89.9	89, 90.3
High	89.1, 90.7	90.2, 93.2	91.3, 93.7
