One of the occupational hazards of being an airplane pilot is the hearing loss that results from being exposed to high noise

One of the occupational hazards of being an airplane pilot is the hearing loss that results from being exposed to high noise levels. To document the magnitude of the problem, a team of re- searchers measured the cockpit noise levels in 18 commercial aircraft. The results (in decibels) are as follows (84). Plane Noise Level (dB) Plane Noise Level (dB) (a) Assume that cockpit noise levels are normally distributed. Use Theorem 7.3.4 to construct a 95% confidence interval for the standard deviation of noise levels from plane to plane. (b) Use these same data to construct two one-sided 95% confidence intervals for o.
