**What are conditions necessary to calculate a confidence**

It is related to the level of confidence that we are working with for our confidence interval. Any percentage less than 100% is possible for a level of confidence, but in order to have meaningful results, we need to use numbers close to 100%. Common levels of confidence are 90%, 95% and 99%.... A 95% confidence interval for the standard normal distribution, then, is the interval (-1.96, 1.96), since 95% of the area under the curve falls within this interval.

**What are conditions necessary to calculate a confidence**

Assuming that the relevant proportion is the same in both Australia and America, use this data to find an approximate 95% confidence interval for the percentage of people in these countries who use an alternative operating system. Interpret this interval... Suppose that we wish to know with 95% confidence the percent of the electorate in a county that identifies itself as Democratic. We conduct a simple random sample of 100 people in this county and find that 64 of them identify as a Democrat.

## How To Find A 95 Confidence Interval Statistics

Assuming that the relevant proportion is the same in both Australia and America, use this data to find an approximate 95% confidence interval for the percentage of people in these countries who use an alternative operating system. Interpret this interval

- Therefore if you are looking at say a 95% confidence interval in the results, it could mean that the final result would be 30-38%. If you want a higher confidence interval, say 99%, then the uncertainty in the result would increase; say to 28-40%.
- Thus, the 95% confidence interval is (75 – 3.92, 75 + 3.92) = (71.08, 78.92). Since the population mean, 80, is outside the interval, we reject the null hypothesis. Since the population mean, 80, is outside the interval, we reject the null hypothesis.
- Therefore if you are looking at say a 95% confidence interval in the results, it could mean that the final result would be 30-38%. If you want a higher confidence interval, say 99%, then the uncertainty in the result would increase; say to 28-40%.
