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.How should the data be analyzed?
A)Completely randomized design
B)Randomized block design
C)2 x 2 factorial design
D)Levene's test

The study design involves two factors, building signs (maps versus wall signage) and starting location (inside versus outside the building), each with two levels. This suggests a 2 x 2 factorial design, where each subject is exposed to both factors in a random order. The travel time data can then be analyzed using a two-way ANOVA to test for main effects of each factor and their interaction, as well as any potential differences in travel time between subjects.
