On your first day on the job, your boss asks you to conduct a hypothesis test about the mean dwell time of a new type of UAV. Before you arrived, an experiment was conducted on ? = 5 UAVs (all of the new type) resulting in a sample mean dwell time of ?1 = 10.4 h????. The goal is to conclusively demonstrate, if possible, that the data supports the manufacturer’s claim that the mean dwell time is greater than 10...
