**3.3 Confidence Intervals and Hypothesis Testing Flashcards**

If you use a bigger net (99% confidence interval), you will have higher confidence that your net has the fish. But your boss won't be happy to receive a 100 feet long fish net for a dead fish. But your boss won't be happy to receive a 100 feet long fish net for a dead fish.... 23/09/2009 · If your p < 0.05 and you REJECT the null hypothesis, then you have a risk of 5% of having rejected it when it had to be accepted, or a 95% of confidence of …

**How to Interpret this Confidence Interval? StatsXchanger**

All values in the confidence interval are plausible values for the parameter, whereas values outside the interval are rejected as plausible values for the parameter. In the Physicians' Reactions case study, the 95% confidence interval for the difference between means extends from 2.00 to 11.26.... Video: The Relationship Between Confidence Intervals & Hypothesis Tests Quantifying population information by testing a small sample is a marvelous mathematical invention.

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.... 24/03/2013 · Since we have a two-sided confidence interval, half of the area outside the confidence interal--.02--will be above the confidence interval and half below it. So let's find that value for plus/minus z. You can look up the probability in your tables or use this calculator.

### In a previous post, I talked about p-values – what they tell you and what they don’t tell you. Quick recap since talking about confidence intervals is related to p-values: p-values ONLY tell you whether a research result is statistically significant or not based on the a priori alpha level.
