 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 ofAssemblers One-HourProduction (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.

 b. A scatter diagram is provided below. Based on it, does there appear to be any relationship between the number of assemblers and production?
 (Click to select)YesNo , as the number of assemblers (Click to select)increasesdecreases, so does the production.
 c. Compute the correlation coefficient. (Negative amounts should be indicated by a minus sign. Round sx, sy and r to 3 decimal places.)
