How hypothesis testing and the use of confidence intervals are the same?
They are related but they are NOT the same.
What is meant by the term confidence intervals?
Confidence intervals represent a specific probability that the "true" mean of a data set falls within a given range. The given range is based off of the experimental mean.
What are the 3 confidence intervals?
There are an infinite number of confidence intervals; different disciplines and different circumstances will determine which is used. Common ones are 50% (is the event likely?), 75%, 90%, 95%, 99%, 99.5%, 99.9%, 99.99% etc.
What command is used to obtain double interval from normal interval?
To obtain a double interval from a normal interval in statistical analysis, you can use the command for confidence intervals, typically found in statistical software. For example, in R, you can use the t.test() function and specify the conf.level parameter as 0.95 for a normal interval, and 0.99 for a double interval. In Python, the scipy.stats library's t.interval() function can be utilized similarly to compute intervals with different confidence levels. Adjusting the confidence level effectively changes the width of the 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 are the Statistics in pathology?
confidence intervals
What is Confidence Intervals of Degree of Confidence?
, the desired probabilistic level at which the obtained interval will contain the population parameter.
What has the author Esa I Uusipaikka written?

What is meant by the term confidence intervals?
Confidence intervals represent a specific probability that the "true" mean of a data set falls within a given range. The given range is based off of the experimental 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.
What is the term used in Confidence intervals to refer to twice the margin of error?
Length
How do the confidence intervals affect a business decision?
If you are a good business man then they don't.
What is Confidence Intervals of Interval Estimate?
An open interval centered about the point estimate, .
What are the 3 confidence intervals?

What is Confidence Intervals of Standard Error?
The standard deviation associated with a statistic and its sampling distribution.
