Been quite a few years since I have done ANY real stats analysis, so I'm not completely certain that I am interpreting my results correctly.

I am trying to determine if two sets of data are the same, using Minitab. The results are:

Two-Sample T-Test and CI: Inside, Outside

Two-sample T for Inside vs Outside

N Mean StDev SE Mean

Inside 10 0.730 0.192 0.061

Outside 10 0.906 0.132 0.042

Difference = μ (Inside) - μ (Outside)

Estimate for difference: -0.1760

95% CI for difference: (-0.3308, -0.0212)

T-Test of difference = 0 (vs ≠): T-Value = -2.39 P-Value = 0.028 DF = 18

Both use Pooled StDev = 0.1648

Based on the above, am I correct to assume that since both the lower and upper limit of the 95% CI is < 0, that this supports the null hypothesis (i.e. Inside and Outside are the same)?
