Confidence intervals: What they are (not)
Published:
Recently at my work, I was asked to assist in determining the correct formula for determining a confidence interval of an unknown quantity from a bunch of random samples. In particular, given random samples drawn from two different normal distributions, the task was to determine the confidence interval for the ratio of the means of those two distributions. My coworker (whose job it was to present this information) had found a formula somewhere online by googling, but wasn’t sure it was correct and asked me to check it.
