... integrand's surface equals its mean value times the area of the integration region. (This is true! Think about it for a while, if it is not obvious. You may want to think in terms of some simple one-dimensional examples first, or recall the mean-value theorem from Calculus). So now the problem can b ...

Confidence Interval Estimation of the Mean—Population Mean
... You use a t distribution until you get to 30 or more df—then it starts to resemble the normal curve, and you can go back to the Z table. Assumptions for using t: Assume the samples are from a normal population Estimate the population SD with the sample sd. Use the t rather than the z. Here’s the for ...
