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.
The limit of (x2â1) (xâ1) as x approaches 1 is 2. And it is written in symbols as: So it is a special way of saying, ignoring what happens when we get there, but as we get closer and closer the answer gets closer and closer to 2. As a graph it looks like this: So, in truth, we cannot say what the value at x=1 is. But we can say that as we approach 1, the limit is 2.
