-dstdize- is a command, not a function.
Before you proceed further, note that the confidence intervals appear
to be of essentially zero length. That seems implausible, but if it's
true, any difference you like is significant at conventional levels.
Getting a P-value is moot. However, I'd be suspicious without being
sure that the instructions were correct.
