case0301

Does dropping silver iodide onto clouds increase the amount of
 rainfall they produce? In a randomized experiment, researchers
 measured the volume of rainfall in a target area (in acre-feet) on 26
 suitable days in which the clouds were seeded and on 26 suitble days
 in which the clouds were not seeded.
