A 95% confidence interval of 1.46–2.75 around a point estimate of relative risk of 2.00 gives the likely range of values for the true relative risk and indicates that a relative risk of less than 1.46 or greater than 2.75 can be ruled out with 95% confidence.... If you want to take six confidence intervals from the same data, and have 95% confidence that they’re all correct, then the confidence level for each of the six CIs must be the sixth root of 95%, about 99.1%.

## How To Tell If You Refject From Confidence Interal

### Confidence intervals are calculated from the same equations that generate p-values, so, not surprisingly, there is a relationship between the two, and confidence intervals for measures of association are often used to address the question of "statistical significance" even if a …

- A confidence interval is an interval within which a parameter is expected to lie. If we say that the 95% confidence interval for the population mean is 10 < #mu# < 22 , it means that
- When the interval and confidence level are put together, you get a spread of percentage. In this case, you would expect the results to be 35 (38-3) to 41 (35+3) percent, 95% of the time. In this case, you would expect the results to be 35 (38-3) to 41 (35+3) percent, 95% of the time.
