To find the confidence interval for a given degree of freedom, you first need to determine the sample mean and standard deviation. Then, using the appropriate t-distribution table (or calculator) for your specified confidence level and degrees of freedom (which is typically the sample size minus one), you can find the critical t-value. Finally, you can calculate the confidence interval using the formula: ( \text{Confidence Interval} = \text{Mean} \pm (t \times \frac{\text{Standard Deviation}}{\sqrt{n}}) ), where ( n ) is the sample size.

What is the confidence level for a confidence interval of 46.8 to 47.2?
The confidence level for a confidence interval cannot be determined solely from the interval itself (46.8 to 47.2) without additional context, such as the sample size or the standard deviation of the data. Typically, confidence levels (e.g., 90%, 95%, or 99%) are established based on the statistical method used to calculate the interval. To find the exact confidence level, more information about the underlying statistical analysis is needed.
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 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.
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 interval for a set of data?
You find the the smallest and largest values. The interval is the largest minus the smallest.
How do you find The margin of error for the confidence interval is?
Generally speaking an x% confidence interval has a margin of error of (100-x)%.

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 can you find greenwich lunitidal interval for Piraeus?

How do you find the interval for a set of data?
You find the the smallest and largest values. The interval is the largest minus the smallest.
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
How do you find an interval on a graph?
to find an interval you have to subtract the first two number from each other for example 5 10 15 20 the interval for this set of data is 5
