n a study designed totest the effectiveness of magnets for treating back​ pain, 3535patients were given a treatment with magnets and also a shamtreatment without magnets. Pain was measured using a scale from 0​(no pain) to 100​ (extreme pain). After given the magnet​treatments, the 3535 patients had pain scores with a mean of 12.0and a standard deviation of 2.2. After being given the sham​treatments, the 3535 patients had pain scores with a mean of 10.2and a standard deviation of 2.6
Construct the 90​% confidence interval estimate of the mean painscore for patients given the sham treatment.
What is the confidence interval estimate of the population meanμ​?
