We actually seem to come to the same conclusion, with only the 1.92 and 1.96 difference.
So your interval [-27.15, +27.15]
This is not the confidence interval though because is strictly about the mean. Probably this has a name in statistics though.
But please look it up.
Sorry. The posts were coming fast and I was behind the thread, and I tried to delete this response before I started my shift, but I guess it missed.
I agree with this range.
EDIT: The CI should be symmetric about the mean. We're using a normal distribution, which is symmetrical about the mean, to model the outcome.
