In the case of a one-sided alternative, the sign of the t-statistic matters A LOT. A negative sign implies that the sample mean is less than the hypothesized mean. This would be evidence against the null hypothesis IF (and only if) the alternative was that the true mean is LESS than the hypothesized value.
