@mmatusevici1,
For the T test, you look at how suprising the results you obtained are assuming your null hypothosis is true.
We would look up our critical value on our T table. 9 degree of freedon, at the .05 significance level is 2.26
So if we get anything that is more surprising than 2.26, we would reject the null hypothesis, because we obtained something that is unlikely to happen if the null hypothesis is true.
However in this case our t value (which is a measure of how unlikely our results are) is less than the critical level (2.23 <2.26) therefor we will not reject the null hypothesis.
