b) An environmental scientist monitors the levels of contaminants in the emissions from the smokestacks of three steel mills. Contaminant levels are measured at ten randomly chosen times for each mill. The goal is to determine if there are significant differences in the mean levels of contaminants produced by the factories, and to identify which means. differ.

Attach the relevant output to support each of your answers. At a 5% significance level, determine if there are significant differences in the mean contaminants' levels produced by the factories. If there are significant differences, identify which pairs of factories have different mean contaminants levels.
