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 subassemblies. 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. One-Hour Number of Production Assemblers (units) 2 ............ 15 4 ............ 25 1 ............ 10 5 ............ 40 3 ............ 30 The dependent variable is production; that is, it is assumed that different levels of production result from a different number of employees. a. Draw a scatter diagram. b. Based on the scatter diagram, does there appear to be any relationship between the number of assemblers and production? Explain. c. Compute the correlation coefficient.
