Answer:Minimum percentage = 88.89%

Step-by-step explanation:We are

given the followingin the question:Mean, μ = 95 dB

Standard Deviation, σ = 8 dB

Chebyshev’s rule:We have to find the minimum percent of data lying within 3 standard deviations of the mean.

Putting values, we get,

Thus, minimum 88.895 of data lies within 3 standard deviations of the mean.
