from given data n= 12
=80/12=6.667
SE=s/√(n-1) = 2.498/√11=0.7532
=0.01
ndf=12-1=11
from table ,critical value of t ,in case of two tailed
corresponding to degree of free 11 and =0.01
= 3.10581
hence 99% confidence interval :
t SE
=6.6673.106×0.7532
=6.6672.3394
=(4.3276 ,9.01)
so,answer to question asked is :
4.3<
<9.0
