Question 223690: What information is necessary to calculate a confidence interval? Is the size of the population relevant when one is determining the sample size for a confidence interval? What does increasing your level of confidence do to the interval estimate? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! What information is necessary to calculate a confidence interval?
sample mean or sample proportion
standard error which depend on z or t, sigma or s, and n
------------------------------------------------------------
Is the size of the population relevant when one is determining the sample size for a confidence interval?
No
-------------------------------------------------------------
What does increasing your level of confidence do to the interval estimate?
If you want the confidence to increase the interval estimate will increase
in size.
