Question 757740
You have produced a confidence interval for your supervisor, and she says, "This interval is too wide to be of any practical value." What ae your options for producing a narrower interval in the next study of this same type?
----
Since the width of the CI is ALWAYS 2*(the margin of error)
and, since the length of ME inversely related to the sample size,
increase the sample size so the CI will be narrower.
