A group of researchers is asked to check whether the average weight of penguins in a certain colony has changed since last year. Last year, the average weight was 5.5 pounds. This year, they find an average weight of 5.3 pounds. If it is later discovered that the researchers made a type II error, what happened? The researchers decided that the average weight of the penguins did change, but it later turned out that it did not. The researchers decided that the average weight of the penguins did not change, but it later turned out that it did. The researchers were not able to arrive at a conclusion and had to repeat their work with a larger sample size.
