A set of reliability testing data for a special equipment was obtained and the ordered ages at failure (hours) were: 8.3, 13, 16.9, 20.1, 23.8, 26.5, 29.8, 33.2, 36.5, 41, 45.1, 51.7, 61.3. Assume that these times to failure are normally distributed. Estimate the equipment reliability and hazard function at age 25 hours.
