In a study designed to test the effectiveness of magnets for treating back pain ,40 patients were given a treatment with magnets and also a sham treatment without magnets. Pain was measured using a scale from 0 (no pain) to 100 (extreme pain) . After given the magnet treatments, the 40 patients had pain scores with a mean of 12.0 and a standard deviation of 2.1. After being given the sham treatment the 40 patients had pain scores with a mean of 10.4 and a standard deviation of 2.5.
c-compare the results. Does the treatment with magnet appear to be effective?
