hypotheses H0 was rejected. Obviously, this confident interval starts with 2.5% and ends 97.5% which gives us 95% of the items between this interval. In the sorted array of our observations we should find 2.5% and 97.5% percentiles: p1 and p2. If p1 <= 30.0 <= p2, then we weren’t able to reject H0.
