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 9 during a one-hour period. Then 4 employees assembled them. They produced 15 during a one-hour period. The complete set of paired observations follows.

 Number of Assemblers One-Hour Production (units) 2 9 4 15 1 4 5 16 3 11

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