In a hypoth. test using a t statistic, what is the influence of a large sample standard deviation?

-Can`t determine w/o more info.
-The size of the standard dev. has no impact on outcome of the hyp. test.
-Larger standard deviation tends to increase the likelihood of rejecting the null hypothesis.
-Bigger standard deviation tends to lower the likelihood of rejecting the null hypothesis.
