A number of different machines can manufacture a certain steel
rod according to the specifications of a company. The company
needs to buy the machine for which the average daily production is
the greatest. The following ANOVA table summarizes pertinent
calculations for this purpose.

Judging by the average daily production and your
p-value, the company will be able to tell whether there is
(or are) some machine(s) whose average daily production is
different from other(s).
