An experimenter flips a coin 100 times and gets 62 heads. Test
the claim that the coin is fair against the two-sided claim that it
is not fair at the level α=.01.
a) Ho: p =
.5, Ha: p ≠
.5; z = 2.40;
Reject Ho at the 1% significance
level.
b) Ho: p =
.5, Ha: p ≠
.5; z = 2.47; Fail to
reject Ho at the 1% significance
level.
c) Ho: p =
.5, Ha: p >
.5; z = 2.40;
Reject Ho at the 1% significance
level.
d) Ho: p =
.5, Ha: p >
.5; z = 2.47; Fail to
reject Ho at the 1% significance
level.
e) Ho: p =
.5, Ha: p ≠
.5; z = 2.40; Fail to
reject Ho at the 1% significance
level.
