Low-back pain

24.   Low-back pain (LBP) is a serious health problem in many industrial settings. The article Isodynamic Evaluation of Trunk Muscles and Low-Back Pain Among Workers in a Steel Factory (Ergonomics, 1995: 2107—2117) reported the accompanying sum- mary data on lateral range of motion (degrees) for a sample of workers without a history of LBP and an- other sample with a history of this malady.

Calculate a 90% con dence interval for the differ- ence between population mean extent of lateral mo- tion for the two conditions. Does the interval sug- gest that population mean lateral motion differs for the two conditions? Is the message different if we use a con  dence level of 95%?
