A fаctоry mаnаger in Nоrthern Canada nоticed that when the building's heating system is used, more employees miss work due to back pain. The manager wonders "Could emissions from the heating system have adverse effects on the workers?" In reality, the heating system probably does not cause back pain. There may be a confouding variable behind the scenes that links using the heating system and back pain. One possible confounding variable in this case is the amount of snowfall. Describe how snowfall meets the definition of a confounding variable by describing how it might be associated with both variables of interest (use of the heating system and back pain).
