Question

When performing a tTest the null hypothesis states which of these?

A. That the results of the research are statistically significant B. That differences observed are caused by some correlation among the variables C. That differences observed in the sample are caused by sampling error (ie: pure chance)

Answer 1

Let's first describe when we do t test.

So this t test we actually do to see whether there is any differences between two samples. We actually look for the difference in means that is whether there is a statistical significant in their difference of means between two groups.

So before performing the test, we take two assumption to land up with a decision. They are null hypothesis and alternate hypothesis.

Hence option A. The results of the research are statistically significant.
