Answer:
Hypothesis: If there is a rat, THEN an elephant will react differently
Independent variable: Presence or absence of rat
Dependent variable: Elephant's reaction
Conclusion: The hypothesis is accepted because rats make an elephant to react.
Explanation:
A hypothesis is a predictive statement about a particular observation made, which is what we're doing next. In this case, a possible statement that suggests solution could be: If there is a rat, THEN an elephant will react differently.
Independent variable is the variable being manipulated in an experiment. The PRESENCE OR ABSENCE OF RATS is the independent variable
Dependent variable is the variable that the experimenter measures. In this experiment, the measurable variable/dependent is the ELEPHANT'S REACTION.
Conclusion of an experiment either rejects or accepts the hypothesis depending on the outcome of the experiment. In this, let it be assumed that the conclusion has been accepted
