We discuss the pairing symmetry of a cobaltate superconductorNa$_x$CoO$_2\cdot y$ H$_2$O by adopting an effective single band model thattakes into account the $e_g'$ hole pockets, as discussed in our previous paper[to appear in Phys. Rev. Lett.] Here we consider the off-site repulsions inaddition to the on-site repulsion considered in our previous study. We showthat the spin-triplet f-wave pairing proposed in our previous study is robustto some extent even in the presence of off-site repulsions. However, f-wavepairing gives way to singlet pairings for sufficiently large values of off-siterepulsions. Among the singlet pairings, i-wave and extended s-wave pairings aregood candidates which do not break time reversal symmetry below $T_c$ inagreement with the experiments.Comment: 12 page
