The production department of Celltronics International wants
to explore the relationship between the number of employees who
assemble a subassembly and the number produced. As an experiment,
two employees were assigned to assemble the parts. They produced 15
during a one-hour period. Then, four employees assembled them. They
produced 25 during a one-hour period. The complete set of paired
observations follows:
Number of Assemblers
