A company that makes commemorative metal wrist bands can save money if they buy strips of metal that are 19 cm long.To see if that is cost effective (i.e., they can mostly use only one strip per band) most people should have wrists less than 19 cm to require only 1 strip to make a wrist band. So, they measured wrist diameters for a sample of 252 people. At a level of p <0.05, is it likely that average wrist size will require only one band?
