Maze learning. Experiment on learning in animals sometimes measure how long it takes mice to find their way through a maze. The mean time is 18 seconds for a particular maze. A researcher thinks that a loud noise will alter the speed at which the mice complete the maze. She measures how long each of 25 mice takes to complete the maze with noise as a stimulus. She finds the average time is 16 seconds with a standard deviation of 5 seconds.
