An environmental group conducted a study to determine whether crows in a certain region were ingesting food containing unhealthy levels of lead. A biologist classified lead levels greater than 6.0 parts per million (ppm) as unhealthy. The lead levels in a random sample of 23 crows in the region were measured and recorded. The mean lead level of the crows in the sample was 4.90 ppm and the sample standard deviation was 1.12 ppm. Construct and interpret a 95% confidence interval for the mean lead level of the crows in the region. Be sure to go through the entire PANIC process.
