DETERMINING SAMPLE SIZE
See Subcourse MD0707, Statistical Sampling I, for the procedure to determine
a. The sample size for internal temperature examination will be expressed in
shipping containers. The lot size will be the number of shipping containers. Inspection
Level S-2 is used.
b. The sample unit for verification of grade and weight of individual eggs is 100
shell eggs from each sample case. As we have seen, a case is defined as 30 dozen
eggs. When eggs are packed in other than 30-dozen cases, the appropriate
multiplication factor is used to calculate the effective number of cases, the equivalent to
30-dozen cases. See figure 2-3. This furnishes the lot size.
