It is common knowledge that a fair coin lands heads up 50% of the time and tails up 50% of the time. For fair coins, a

probability of O is assigned to the coin landing on its edge. But what if several coins were glued together? A teacher claims
that if 10 pennies were glued together and flipped many times, the penny stack would land on heads 25% of the time, tails
25% of the time, and on its edge 50% of the time. To investigate this claim, a student glues 10 pennies together and flips
the stack 200 times. The student would like to know if there is convincing evidence that the distribution differs from what
the teacher claimed. What are the appropriate hypotheses?
