An aluminum master alloy manufacturer produces
grain refiners in ingot form. The company produces the prod
uct in four furnaces. Each furnace is known to have its own
unique operating characteristics, so any experiment run in the
foundry that involves more than one furnace will consider fur
naces as a nuisance variable. The process engineers suspect
that stirring rate affects the grain size of the product. Each fur
nace can be run at four different stirring rates. A randomized
block design is run for a particular refiner, and the resulting
grain size data is as follows.
a Is there any evidence that stirring rate affects grain size?
