A. There is insufficient evidence to conclude that the difference between the mean traveling time for the different starting locations depends on the types of signs.
B. There is sufficient evidence to conclude that the difference between the mean traveling time for the different types of signs depends on the starting locations.
C. There is sufficient evidence to conclude that the relationship between traveling time and the types of signs depends on the starting locations.

A campus researcher wanted to investigate the factors that affect visitor travel time in a complex,multilevel building on campus. Specifically, he wanted to determine whether different building signs (building maps versus wall signage) affect the total amount of time visitors require to reach their destination and whether that time depends on whether the starting location is inside or outside the building.Three subjects were assigned to each of the combinations of signs and starting locations, and travel time in seconds from beginning to destination was recorded. An Excel output of the appropriate analysis at 1%level of significance is given below:
