In a certain experiment, 50 ECE graduating students are selected randomly and their time to finish a 100-item exam in MATH is recorded. The average time for these students is 3 hrs and 20 minutes. In the previous years, the population standard deviation of the graduating students in taking the said exam is 20 minutes. Find a 99% confidence interval for the population mean of the current graduating ECE students.
