An engineer has built a simulation model of a small factory, run an experiment with the model using 15 replicates, and determined at 90% confidence that the mean time an entity spends in the system is in the range of 24 min to 28 min. The data are normally distributed. Based on this information, what can the engineer say about entity time-in-system? A -The population mean time-in-system must be in the interval 24 min to 28 min. B- The largest mean time-in-system for any one of the 15 replicates was 28 min. C- If the engineer were to run a 16th replicate, the mean time-in-system would be in the interval 24 min to 28 min. D. The probability that the population mean time-in-system is greater than 28 min can be estimated as 5%.
