For a sample of 23 operating rooms taken in a hospital study, the mean noise level was 37.9 decibels, and the standard deviation was 7.6. Find the 95% confidence interval of the true mean of the noise levels in the operating rooms. Assume the variable is normally distributed. Use a graphing calculator and round the answers to at least one decimal place.
