Noise levels at various area urban hospitals were measured in decibels. The mean of the noise levels in 99 corridors was 61.77 decibels, and the standard deviation of the population was 7.05. Find the upper boundary of the 95% confidence interval of the true mean. Only the final answer should be rounded-off to TWO decimal places.
