Motorco produces electric motors for use in home appliances. One of the company’s production managers is interested in examining the relationship between the dollars spent per month in inspecting finished motor products and the number of motors produced during that month that were returned by dissatisfied customers. He has collected the data in the file P2_18.XLS to explore this relationship for the past 36 months. Produce a correlation measure for these two variables and interpret it for this production manager.
