A decibel is a unit that measures the loudness of a sound. The larger the number of decibels, the louder the sound. The Occupational Safety and Health Administration (OSHA) has limits of exposure for different sound levels, as seen in the table below: Sound Level Maximum Allowed Duration
(decibels) [left] per Work Day (hours) [right]

90 | 8

92 | 6

95 | 4

100 | 2

105 | 1

110 | 0.5

115 | 0.25

Suppose a manager wants to know how long a worker can be exposed to a sound level of 120 decibels. Find a line of best fit. Describe how well it fits the data and whether it can make a good prediction for the manager.
