Hi,

I would like to be able to manipulate the output of a OneSampleZTest for the Confidence Interval.  Here is what I have right now:

CI:=OneSampleZTest(S,mu,sdev,confidence=0.95,output='confidenceinterval');

The output for this is, for example: 1490.90920124091 .. 1497.18170785000

I interpret this to be a string.  What I would like is to split this into two separate outputs, say:

CI_lower:=some command to produce an output of 1490.90920124091

CI_upper:=some command to produce an output of 1497.18170785000

I have tried a number of commands in the StringTools package and I keep getting various errors.

Thanks.
