Which of the following statements best describes a prediction?
the number of deformed frogs in five ponds that are polluted with chemical X is higher than the number of deformed frogs in five ponds without chemical X
if the water in a pond has lower levels of pesticide then there will be less deformed frogs
the number of deformed frogs is not affected by the presence of chemical X in the pond

experiment
observation
evidnece

asking questions
You are conducting an experiment. The following statement is your hypothesis: The average number of deformed frogs in ponds that are polluted is greater than the average number of deformed frogs in non-polluted ponds. Analyze the data in the image. What conclusion can you draw from this data?
The hypothesis is true, the average number of deformed frogs in the polluted ponds and non-polluted ponds is almost the same.
The hypothesis is true, the polluted ponds have more deformed frogs than the non-polluted ponds.
The hypothesis is false, the average number of deformed frogs between polluted ponds and non-polluted ponds is almost the same
The hypothesis is false, the polluted ponds have more deformed frogs than the non-polluted ponds.
