## Homework Statement

I know the sample size n, the observed sample mean x, and the observed sample standard deviation s. I need to determine a value v such that I'm 95% confident that the average is v or less.

## The Attempt at a Solution

If I calculate the 95% confidence interval, then I know that 95% of the resulting intervals will contain the true mean. Does the upper bound of the 95% confidence interval also tell me that this mean will be less than or equal to the upper bound with 95% confidence? Am I thinking about this the wrong way? Thanks
