of alfalfa plants in the pasture had the following copper contents (measured in my 5. A farmer is studying the copper content of some alfalfa plants in one of her pastures. And 10.7 6.4 12.5 8.5 10.8 8.5 113 10.2 85 7.9 Assume the true population standard deviation of the copper content of alfalfa plants is 2 ye, and that we copper content of the plants is normally distributed. If the alfalfa in the pasture has mean copper content significantly less than 10 ppm, the pasture should be not used for dairy cows but rather for live goats, who a. State H, and H, for a hypothesis test that the meano copper content of the plant is significantly less than 10 ppm.
