Question:

A randomized block design is used to compare k = 3 radar systems for detecting airborne objects. A total of b = 8 objects are flown toward the radar stations and the distances at detection by the radar systems are recorded in DS 11.2.4. Perform hand calculations to investigate whether there is evidence of any difference between the radar systems.
