I observed 1 success in 1497 trials so I use: My null hypothesis p=0.0033 is outside the confidence interval (> 0.00316) so I am tempted to reject it, but then when I look at the p-value, it is 0.1062 (> 0.10) which would say I cannot reject it. Following Agresti and Coull, the Wilson interval is to be preferred and so is the default.

The returned object has an attribute called args, which is a list holding the test arguments. I have a question regarding binom.test() in R (3.3.3 on Windows 10): I have a null hypothesis that the p(success)=0.0033 and I want to know whether I can reject this null hypothesis at a signficance level of 0.10 (two-tailed).
