The production department wants to explore the relationship between the number of employees who assemble a subassembly and the number produced. The complete set of paired observations follows:
Number of Assemblers One Hour Production (units)
2 15
4 25
1 10
5 40
3 30
A- Draw a scatter diagram
B- based on the diagram, does ther appear to be any relationship between assemblers and production.
C- Compute the coefficient of correlation.
D- Compute the coefficient of determination and evaluate the strength of relationship.
