A grоup оf physicаl therаpists investigаted the effect оf home exercise on back pain reduction in females aged 45-65 years. The study recruited 100 volunteers who chose to perform either a 20-minute or a 40-minute exercise routine daily for one month and then reported the effect on their back pain using a standard scale. At the end of one month, participants who exercised for 20 minutes had a significantly higher pain reduction than those who exercised for 40 minutes. The therapists conducting the study concluded that a 20-minute exercise routine would reduce back pain for females aged 45-65 years. Based on the study design, do you think that the conclusions are reasonable?
