player who is known to be a 0.250 career hitter, but this winter he
trained very hard and believes that he has improved (that is, his
probability of getting a hit has gone up from 0.250). He wants to
convince his manager of the change so that he may get a pay
raise.
Data: The manager offers to give Tim an
opportunity to demonstrate his performance in 30 at-bats, and out
of the 30 at-bats Tim gets 10 hits.
Let p represent Tim's probability of getting a hit,
and let p^represent the proportion of hits in 30 at-bats.
a) Which of the following are the appropriate set of
hypotheses?
