Why confidence interval useful?
Why confidence interval is useful
What happens to the confidence interval if you increase the sample size?
The confidence interval becomes smaller.
Is confidence interval and confidence limits are same thing?
no,these are not the same thing.The values at each end of the interval are called the confidence limits.
What happens to the width of the confidence interval when you are unable to get a large sample size?
The width of the confidence interval increases.
Is it better to have a wide confidence interval or a narrow confidence interval?
Narrow because there is less of a chance for people to mess up
Which three elements are necessary for calculating a confidence interval?
Variance, t-value, sample mean
Does the population mean have to fall within the confidence interval?
No. For instance, when you calculate a 95% confidence interval for a parameter this should be taken to mean that, if you were to repeat the entire procedure of sampling from the population and calculating the confidence interval many times then the collection of confidence intervals would include the given parameter 95% of the time. And sometimes the confidence intervals would not include the given parameter.

Why confidence interval is useful
What happens to the confidence interval if you increase the confidence level?
The confidence interval becomes wider.
What Confidence interval is 0.05 alpha?
how are alpha and confidence interval related
The width of a confidence interval is equal to twice the value of the margin of error?
No. The width of the confidence interval depends on the confidence level. The width of the confidence interval increases as the degree of confidence demanded from the statistical test increases.
What happens to the confidence interval as the mean decreases?
The confidence interval is not directly related to the mean.
What happens to the confidence interval if you increase the sample size?
The confidence interval becomes smaller.
Is a 95 percent confidence interval for a mean wider than a 99 percent confidence interval?
No, it is not. A 99% confidence interval would be wider. Best regards, NS
What is the most controllable method of increasing the precision of or narrowing the confidence interval?
Confidence intervals represent an interval that is likely, at some confidence level, to contain the true population parameter of interest. Confidence interval is always qualified by a particular confidence level, expressed as a percentage. The end points of the confidence interval can also be referred to as confidence limits.
Is confidence interval and confidence limits are same thing?
no,these are not the same thing.The values at each end of the interval are called the confidence limits.
What happens to the width of the confidence interval when you are unable to get a large sample size?
The width of the confidence interval increases.
