The P-value for a hypothesis test is 0.081. For each of the
following significance levels, decide whether the null hypothesis
should be rejected.
a. alph-0.10 b. alpha=0.05
a. Determine whether the null hypothesis should be rejected for
alphaequals0.10.
A. Reject the null hypothesis because the P-value is greater than
the significance level.
B. Do not reject the null hypothesis because the P-value is
greater than the significance level.
C. Do not reject the null hypothesis because the P-value is equal
to or less than the significance level.
D. Reject the null hypothesis because the P-value is equal to or
less than the significance level.
b. Determine whether the null hypothesis should be rejected for
alphaequals0.05.
A. Reject the null hypothesis because the P-value is equal to or
less than the significance level.
B. Reject the null hypothesis because the P-value is greater than
the significance level.
C. Do not reject the null hypothesis because the P-value is
greater than the significance level.
D. Do not reject the null hypothesis because the P-value is equal
to or less than the significance level.
Let the level of significance be denoted by . The rule is that :-
Given; P-value = 0.081
=0.10 > P-value D. Reject the null hypothesis because the P-value is equal to or less than the significance level.
=0.05 < P-value C. Do not eject the null hypothesis because the P-value is greater than the significance level.
