You should do an F-test for this problem: In a hospital, it was found that the standard deviation of sound levels from 20 randomly selected areas was 4.1 dBA, and the standard deviation from a different 24 randomly selected areas was 7.5 dBA. Use α=0.05 and check the claim that there is a difference between the two standard deviations.
