Decibel Level Examples: How Loud are Sounds at Different dB Levels? | TSP

SOLVED: The ideal (daytime) noise-level for hospitals is 45 decibelswith a standard deviation of 10 db; which is to say, this may notbe true. A simple random sample of 75 hospitals at a moment duringthe day gives a mean noise level of 47 db. Assume that the standarddeviation of noise level for all hospitals is really 10 db. Allanswers to two places after the decimal.(g) How many hospitals must we examine to have 95% confidencethat we have the margin of error to within 0.5 db?(h) How many hospita
