Abstract: Let $ {M^n},n \geq 3$, be an oriented minimally immersed complete hypersurface in Euclidean space. We show that for $ n = 3,4,5,{\text{ or }}6$, the index of $ {M^n}$ is finite if and only if the total scalar curvature of $ {M^n}$ is finite, provided that the volume growth of $ {M^n}$ is bounded by a constant times $ {r^n}$, where $ r$ is the Euclidean distance function. We also note that this result does not hold for $ n \geq 8$. Moreover, we show that the index of $ {M^n}$ is bounded by a constant multiple of the total scalar curvature for all $ n \geq 3$, without any assumptions on the volume growth of $ {M^n}$.
