Evaluate Clara’s practices for the prevention of parasite infestation in the following scenario. Last year, Clara lost thousands of dollars when her sheep herd was infested with tapeworms. She has always been diligent about keeping the pens clean and ensuring a proper diet. She has also always given her sheep plenty of freedom by allowing them to wander day and night, and she even protects them from the hot weather by putting them out to graze in the cooler evening hours. She hopes that this year the herd will be more fortunate.

Ali hypothesized that increasing fertilizer would increase plant growth. four groups of thirty similar plants were given 0 to 15 ml of fertilizer, as shown in the graph. the change in plant height for each group over a two-week period was averaged and recorded. plant group fertilizer added (ml) avg. growth (cm) a 0 4 b 5 6 c 10 8 d 15 3 what is the best conclusion based on this data? the hypothesis was not supported because the data indicated that fertilizing plants does not improve plant growth. the hypothesis was supported; to get the best growth, use 5 milliliters of fertilizer per plant. the hypothesis was not supported; the data indicated that too much fertilizer can inhibit plant growth. the hypothesis was supported; to get the best growth, use 15 milliliters of fertilizer per plant.
