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

AssemblersOne-Hour

Production (units)215425110540330

The dependent variable is production; that is, it is assumed that the level of production depends on the number of employees.

A scatter diagram is provided below. Based on it, does there appear to be any relationship between the number of assemblers and production?

, so about

percent of the variation in production is explainedby the variation in the number of assemblers.
