Answer 1

In 2013, a New York high-school statistics class made national news when they investigated whether Double Stuf Oreos truly had double the “stuf.” They took filling from 10 regular Oreos, massed it as one gob, and divided by 10. They did the same with the Double Stuf cookies. The students divided the mean mass for the Double Stuf by the mean mass for the regular cookies and got 1.86, indicating that the Double Stuf cookies did not have double the filling.
