Bootstrap CI: One Sample

Resample your data with replacement many times, recording the mean of each resample. The histogram that builds up is the bootstrap distribution of the sample mean — read a confidence interval for the population mean off its middle (e.g., the middle 95%). This is an estimation tool: no hypotheses, no p-value.
