    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 there 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.
