A biologist hypothesizes that restricting food from mice will decrease their activity. He designs an experiment in which he observes the activity of 50 mice under restricted food regimens.Which of the following is true about his study?
A hypothesis needs to be validated or rejected, so the first sentence is true because it's his point of view that he wants to investigate. It wouldn't be truth if it's thesis (not hypothesis), because he would have no proof for that.
