Explanation:
Noise levels at 5 airports = 147,123,119,161,136
Mean noise level
Variance of noise level
Standard deviation,
a) Confidence interval is given by
For 99% confidence interval Z = 2.576,
Number of noises, n = 5
Substituting
The 99% confidence interval for the mean noise level = [122.44, 151.96]
b) Sample standard deviation
Sample standard deviation, s = 17.3dB
