A dowsing rod is a Yor "L" shaped instrument that some believe can find ground water. Many dowsers today use a pair of simple L-shaped metal rods. One rod is held in each hand, with the short arm of the L held upright, and the long arm pointing forward. When something is found, the rods cross over one anoth making an "X" over the found object. Skeptics of dowsing conducted an experiment to see if dowsing rods could find ground water. Five identical 3 foot by 3 foot plots of land were sectioned off and a containen goodness-of-fit test follow. Choose the correct null and alternative hypothesis. O Cick the icon to view the summary and output. water was buried in one of the plots. A summary of the experiment results and the output for the OA. Ho: The dowsing rods work better at locating ground water than guessing. Ha: The dowsing rods work no better at locating ground water than guessing. OB.
