Researchers are studying blood lead levels in two groups: children living near a highway with $n=35$, $\bar{x}=8.2\mu \text{g/dL}$, and $s=3.9\mu \text{g/dL}$, and children living in rural areas with $n=35$, $\bar{x}=2.7\mu \text{g/dL}$, and $s=1.6\mu \text{g/dL}$. At the $0.05$ significance level, test the claim that the variation in blood lead levels is greater for children living near the highway than for those in rural areas.

There is insufficient evidence to warrant rejection of the claim that the variation in blood lead levels is equal for children living near the highway and those in rural areas.
