The results for the noise sampling in the following table were recorded from your noise dosimeters. All the samples were collected for the full shift using 90 decibels on the A scale (dBA) as the criterion level and a 5 decibels (dB) exchange rate.

Answer the following for each of the locations listed above:

• Convert the results from dBA to percent.
