5.31 Colour Preferences in Mice In a psychol- ogy experiment, a researcher plans to test the colour preference of mice under certain experimental condi- tions. She designs a maze in which the mouse must choose one of two paths, coloured either red or blue, at each of 10 intersections. At the end of the maze, the mouse is given a food reward. The researcher counts the number of times the mouse chooses the red path. If you were the researcher, how would you use this count to decide whether the mouse has any preference for colour?
