Question 1183502: The width of a confidence interval is a measure of its precision. The narrower the confidence interval, the more precise is the interval estimate,and vise versa. Describe any three aspects that influence the precision of the width of a confidence interval of a single population mean. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! the half-interval width is a function directly proportional to confidence , std deviation and inversely proportional to the sample size.
t*s/sqrt(n)
The width is wider (less precise) for larger values of confidence, larger values of variance/std. dev., and narrower for larger value of sample size, all other things being equal.
