Question: Noise Levels in Hospitals. The mean noise level of 20 randomly selected areas designated as "casualty doors" was 63.1 dBA, and the sample standard deviation is4.1 dBA. The mean noise level for 24 randomly selected theaters was \(56.3 \mathrm{dBA}\), areas designated as operating and the sample standard deviation was \(7.5 \mathrm{dBA}\). At \(\alpha=0.05\), can it be concluded that there is a difference in the means?
