An inspector samples cans from a truckload of canned creamed corn to estimate the total number of worm fragments in the truckload. The truck has 580 cases; each case contains 24 cans. The inspector samples 12 cases at random, and subsamples 3 cans randomly from each selected case.

Using (5.20) and (5.24), estimate the total number of worm fragments, along with a 95% CI. Compare the estimated value of the variance from (5.24) with the approximation that is used by SAS software, given in (5.25).
