biologist wants to see if rats running in a maze use some kind of decision process on how to proceed when they come to an intersection. To do so she decides to simulate the situation by assuming the decisions are random, so she creates a “virtual rat” that at each intersection tosses a coin to decide which way to go. She lets the “virtual rat” run the maze 1000 times, and finds the average length run is 14.8 feet, with a standard deviation of 2.4 feet. She then lets a real rat run the maze, and measures the length run to be 13 feet. Explain what conclusion the biologist can make.
