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, 2 employees were assigned to assemble the subassemblies. They produced 11 during a one-hour period. Then 4 employees assembled them. They produced 18 during a one-hour period. The complete set of paired observations follows.

Number of
Assemblers
One-Hour
Production (units)
2 11
4 18
1 5
5 23
3 18

The dependent variable is production; that is, it is assumed that different levels of production result from a different number of employees.
