Here p value is 0.011 and level of significance 
=0.05
The null hypothesis is different samples came from popualtion of same mean
P value is less than
. So null hypothesis is rejected.so different sample do not came
from population of same mean
Option (b) p value 0.011 and reject Ho is correct answer.
