​(Round to three decimal places as​ needed.)
​(c) State the conclusion for the test.
Choose the correct answer below.
A.
Do not reject

Upper H 0

because the​ P-value is less than

the alpha
equals0.05

level of significance.
B.
Reject

Upper H 0

because the​ P-value is less than

the alpha
equals0.05

level of significance.
C.
Reject

Upper H 0

because the​ P-value is greater than

the alpha
equals0.05
