For each of the following exercises carry out the ten-step hypothesis testing procedure for the level of significance. 1. The purpose of a study by Luglie et al.[1], 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, and filled teeth index (DMFT). In a sample of 18 patients the mean DMFT index value was \( 10.3 \) with a SD of 7.3.
