Yоu’re а pаin mаnagement specialist interested in the effect оf a new treatment оn back pain reduction in males aged 40-60 years. You conduct a study in which you recruit 100 men between the ages of 40 and 60 years, all of whom are of normal weight. The men aged 40 to 50 years receive the new treatment, while the men aged 50 to 60 years do not receive the treatment. At the end of the study, you ask all the study participants to assess their back pain. You find that the group that received the treatment had a significantly greater back pain reduction than the group that did not receive the treatment. Did the study use a random selection process from the population of males aged 40-60 years? Did the study use random assignment to experimental groups?
