A) An 85% chance that standing longer hours directly causes increased back pain severity. B) A strong relationship between hours of standing and back pain severity, but not necessarily a cause-and-effect relationship. C) A negative relationship between hours of standing and back pain severity. D) An insignificant relationship between the two variables. LINKS MENTIONED: Did you get this question wrong?!
