Question
Suppose a professional basketball player
historically makes 39% of his three-point field
goals. After a rigorous off-season training, the
.player makes 31 of his 75 three-point field goals
Does this represent significant evidence that the
player's three-point field goal shooting has
?improved
:To do this test, the first step, is
Ho : p= 0.39
H : p> 0.39
.The null hypothesis is right-tailed
Ho : p= 0.39
H : p> 0.39
.The alternative hypothesis is right-tailed
Но : р%3D 0.39
H : p< 0.39
.The alternative hypothesis is left-tailed
Но : р%3D 0.39
H1 : p+0.39
.The alternative hypothesis is two-tailed
