Dear R-help, 

> prop.test(9, 137, p=0.066)

> prop.test(9, 137, p=0.05)

give two different 95% confidence intervals.
I thought the confidence interval calculation
should be independent of testing calculations (and thus
the null hypothesis)?

Splus 2000 has similar problems but give slightly different
answer.

Using R1.3.0 on windows.
