Generally speaking an x% confidence interval has a margin of error of (100-x)%.

99 percent confidence interval Population mean 24.4 to 38.0 find the mean sample?

if the confidence interval is 24.4 to 38.0 than the average is the exact middle: 31.2, and the margin of error is 6.8


How do you find the sample size if you are given the confidence interval and the margin of error as well as the standard deviation?

You can't. You need an estimate of p (p-hat) q-hat = 1 - p-hat variance = square of std dev sample size n= p-hat * q-hat/variance yes you can- it would be the confidence interval X standard deviation / margin of error then square the whole thing


YOU MEET 80 RANDOMLY SELECTED VOTERS AND FIND THAT 54% SUPPORT A CANDIDATE FOR THE LEGISLATURE OF MONAGAS. USING A CONFIDENCE LEVEL OF 95% CALCULATE THE LIMIT OF PERCENTAGE OF VOTERS WHO PREFER THE REFERRED CANDIDATE?

The confidence interval for this problem can be calculated using the following formula: Confidence Interval = p ± z*√(p*(1-p)/n) Where: p = observed proportion (54%) n = sample size (80) z = z-score (1.96) Confidence Interval = 0.54 ± 1.96*√(0.54*(1-0.54)/80) Confidence Interval = 0.54 ± 0.07 Therefore, the confidence interval is 0.47 - 0.61, meaning that we can be 95% confident that the percentage of voters who prefer the referred candidate is between 47% and 61%.


How can one find the LCL (Lower Confidence Limit) for a statistical analysis?

To find the Lower Confidence Limit (LCL) for a statistical analysis, you typically calculate it using a formula that involves the sample mean, standard deviation, sample size, and the desired level of confidence. The LCL represents the lower boundary of the confidence interval within which the true population parameter is estimated to lie.

Will you find the number 89 in the interval 79-89?

Yes, if it is the closed interval. No, if it is the open interval.


How do you find the confidence intervals?

See: http://en.wikipedia.org/wiki/Confidence_interval Includes a worked out example for the confidence interval of the mean of a distribution. In general, confidence intervals are calculated from the sampling distribution of a statistic. If "n" independent random variables are summed (as in the calculation of a mean), then their sampling distribution will be the t distribution with n-1 degrees of freedom.

What is one structure you would find at an active continental margin that you would not find at a passive continental margin?

On an active continental margin, you would be likely to find an active ocean trench. This structure would generally not occur at a passive continental margin.
