Small sample test for mean, Applied Statistics

Assignment Help:

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 ~ t_n-1.
