In a hospital study, it was found that the standard deviation of the sound levels from 26 areas designated as "casualty doors" (sample 1) was 7.1 dBA and the standard deviation of 25 areas designated as "operating theaters" (sample 2) was 4.3 dBA. At a=0.10, can you substantiate the claim that there is a difference in the standard deviations? a) State the hypotheses and identify the claim with the correct hypothesis. 01.
