More generally, the formula for the 95% confidence interval on the mean is: Lower limit = M - (tCL)(sM) Upper limit = M + (tCL)(sM) where M is the sample mean, tCL is the t for the confidence level desired (0.95 in the above example), and sM is the estimated standard error of the mean.
open interval, unbounded interval-an interval that does not include its endpoints. sub-interval-an interval that is included in another interval. set - (mathematics) an abstract collection of numbers or symbols; the set of prime numbers is infinite.
