Degree of confidence represents the probability that the confidence interval captures the true population parameter.

With a degree of confidence of 95%, you have 95% confidence that the true population parameters will be in the confidence interval.

95% is the standard.

If you want 95% confidence that you're capturing the true population parameters, you may sometimes have to report a really wide interval.
