for lead. One possible source of lead is from vehicles that drive around the forest, but this source has gone down in recent years due to elimination of lead tromgasoline. Analysis of Variance can help determine if the differences in mean lead concentrations are meaningful. Use the display below to determine if thereevidence to support the claim that the mean lead concentrations differ significantly among years.

Four different paints are advertised as having the same drying time. To check the manufacturers' claims, five samples were tested for each of the paints. The time in minutes until the paint was dry enough for a second coat to be applied was recorded for each sample. The data obtained follow.
