Calculate an approximate 99.7% confidence interval for the population mean age for government employee interns based on the following sample data: From a sample of 35 government employee interns, the sample mean age is 26.1 years. Assume the population standard deviation is 5.8 years. Assume the distribution of ages is normally distributed. Enter your answer in the format (lower,upper) where "lower" is the lower confidence limit and "upper" is the upper confidence limit. Round your answers to two decimal places. Do not include units in your answers.
