3. A chemical engineer is studying the effects of temperature and catalyst on the percentage of undesired byproduct in the output of a chemical reactor. Orders of testing were determined using random numbers. Percentage of the byproduct is shown in the table below.
Catalyst Temperature, ~
#1 140 150
2.3 1.6
1.3 2.8
#2 3.6 3.0
3.4 3.8
The diagnostic plots recommended in part (c) of section 12.1 were
carried out and showed no significant discrepancies. Can we
conclude (at the 5% level of significance) that catalyst or
temperature or their interaction affects the percent- age of
byproduct?
