##p(x≤11)=1-[p(x=12)+p(x=13)+p(x=14)+p(x=15)]##
##p(x≤11)=1-[0.128505+0.266895+0.3431518+0.205891]=1-0.9444428=0.0556##
##⇒p(x>11)=0.9444##
##p(x≤10)=1-[0.042835+0.128505+0.266895+0.3431518+0.205891]=1-0.9872778=0.0127222##
Since, ##p(x≤11)=0.0556> 0.05## then it falls on the Accepted region and further, ##p(x≤10)=0.0127<0.05## then it falls on the Rejected region. We therefore do not reject the Null hypothesis.
Any insight welcome...
