Answer:
The minimum percentage of noise level readings within 8 standard deviations of the mean is 98.44%.
Step-by-step explanation:
When we do not know the shape of the distribution, we use the Chebyshev's Theorem to find the minimum percentage of a measure within k standard deviations of the mean.
This percentage is:

Within 8 standard deviations of the mean
This means that
. So

The minimum percentage of noise level readings within 8 standard deviations of the mean is 98.44%.
Answer:
1/1 I think I hope this helps
Step-by-step explanation:
The Answer Is B.
To Find The Mean, You Add Up Every Number And Divide By How Many Numbers There Were.
136 + 145 + 123 + 140 + 126 = 670
670 Divided By 5 = 134
The Mean For The 4 Weeks Was 136.
The Mean For The 5 Weeks Was 134.
The Mean Decreased By 2. Your Answer Is B.
280, 509,031 + 10,000,000 = 290, 509,031
200,000,000 + 90,000,000 + 500,000 + 9,000 + 30 +1 is your answer
