A delivery company claims that they deliver their packages in 2 days on average. You have been tasked with verifying their claim by another delivery company. You decide to take a random sample of 10 packages, record their delivery times, find the mean delivery time, and report the results with statistical measures for 95% confidence. You find that the mean time is 2.3 days with a sample standard deviation of 0.35 days.
