Assume that a sample is used to estimate a population mean μμ. Find the 95% confidence interval for a sample of size 388 with a mean of 55.6 and a standard deviation of 14.7. Enter your answer as a tri-linear inequality accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).

 < μμ < 

Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
