Small sample test for mean, Applied Statistics

If the sample size is less than 30, then we need to make the assumption that X (the volume of liquid in any cup) is normally distributed. This forces 814_computation of covariance ungrouped data2.png  (the mean volume in the sample) to be normal.

If V(X) =  1683_small sample test for mean.png  is known, 774_small sample test for mean1.png

If V(X) is not known,  1022_small sample test for mean2.png  ~ tn-1.
