Answer:
Minimum percentage = 88.89%
Step-by-step explanation:
We are given the following in the question:
Mean, μ = 95 dB
Standard Deviation, σ = 8 dB
Chebyshev's rule:
- According to this rule atleast
percent of data lies within k standard deviation of mean.
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.
