Fractional number of workers is due to averaging data from all 

 sampled packing houses. 



According to Table 1, the IPM packing line used a larger number 

 of grader/packers (average of 5.8) than the control (average of 5). 

 Ordinarily, the number of grader/packers would be the same. However, 

 on the same days the samples were taken, several control packing 

 lines were not operating at full grader/packer capacity. 



The problem does not affect the comparison of labor productiv- 

 ity for grader/packers, since productivity is based on volumne of 

 apples packed. The supervisor/carton handler's productivity will 

 be lower for the control fruit, however, since all packing lines 

 were operating at normal levels for these personnel.
