Convert your data to z scores.

Doesn't your suggestion fit only if the curve is standard normal?,
i.e. mean
0, SD 1?
Perhaps my use of integral is incorrect; what I want is the area
under the
curve of a normal distribution, mean 2.05, sd 1.75 for the portion >=
threshold =1, and then the portion < 1

I may be missing something here, but can't you simply use the normal
distribution with mean=proportion z >= some threshold, q=1-p and
variance p(1-p)/n? No integration involved.
As I said, I might be missing something!
