Exercises The purpose of a study by Luglie was to investigate the oral status of a group of patients diagnosed with thalassemia major (TM) One of the outcome measures was the decayed, missing, filled teeth index (DMFT). In a sample of 18 patients ,the mean DMFT index value was 10.3 with standard deviation of 7.3. Is this sufficient evidence to allow us to conclude that the mean DMFT index is greater than 9 in a population of similar subjects? Let a =0.1
