Imagine that a researcher for a large food company believes that he has developed a new drug that increases appetite. He names the drug "EatMore" and designs an experiment to test his hypothesis. He uses two groups of mice: one group is given the drug and the other group given a placebo sugar pill. The appetite levels are assessed by measuring the amount of food consumed by the mice in each group for one week. At the end of the experiment, he reported that on average, mice that received the "EatMore" drug consumed 2.5g of food/day and mice that received the placebo consumed 5g of food/day. Statistical analysis of the data showed the difference to be statistically significant.
