**Hospital Noise Levels:** For a sample of 9 operating rooms taken in a hospital study, the mean noise level was 42.6 decibels and the standard deviation was 10.7. Find the 90% confidence interval of the true mean of the noise levels in the operating rooms. Assume the variable is normally distributed. Round your answers to at least two decimal places.\[ \text{[ ]} < \mu < \text{[ ]} \]**Diagram Explanation:** There is a graphical input box with two empty fields for the lower and upper bounds of the confidence interval. There are also two buttons: one with an 'X' for deleting or clearing values, and another with a circular arrow for resetting or refreshing the input fields.

From the provided information, Sample size (n) = 9 Sample mean (x̄) = 42.6 Sample standard deviation…
