The data below are the ages of a random sample of 8 men in a bar. It is known that the population of ages are normally distributed with a standard deviation of 9. Determine the 94% confidence interval estimate of the population mean.

$$50, \quad 67, \quad 21, \quad 38, \quad 61, \quad 39, \quad 26, \quad 47$$

Note: For each confidence interval, enter your answer in the form (LCL, UCL). You must include the parentheses and the comma between the confidence limits.
