A student wanted to compare two types of commuting options. One type is carpooling and the other is taking a commuter train. It is a common belief that carpooling saves more time. This belief is tested by having 10 students commute to school by each mode of transportation and recording the time of arrival at school each morning. A coin flip was used to determine which type of transportation that a student would use first. Results indicated that there was...
