Two successive flips of a fair coin is called a trial. 100trials are run with
a particular coin; on 22 of the trials, the coin comes up“heads” both
times; on 60 of the trials the coin comes up once a “head” andonce a
“tail”; and on the remaining trials, it comes up “tails” forboth flips. Is this
sufficient evidence ( = : 05) to reject the notion that the coin(and the
flipping process) is a fair one?
