Part 1
Explain what a P-value is. Choose the correct answer
below.
A. A P-value is the value used to designate the
area α in either the left- or right-tail of
the normal curve.
B. A P-value is the number of standard deviations
that the observed proportion is from the proportion stated in the
null hypothesis.
C. A P-value is the probability of observing a sample
statistic as extreme or more extreme than the one observed under
the assumption that the statement in the null hypothesis is
true.
Part 2
What is the criterion for rejecting the null hypothesis using
the P-value approach? Choose the correct answer below.
A.If P-value<α, reject the null hypothesis.
B.If P-value<−zα for a left-tailed test, or
if P-value>zα for a right-tailed test, or
if P-value<−zα/2 or P-value>zα/2 for
a two-tailed test, then reject the null hypothesis.
C.If P-value>α, reject the null hypothesis.
