Suppose that the average number of years to graduate at a university is 4 years with a standard deviation of 0.5 years.  Assume a mound-shaped (i.e. bell-shaped) distribution for years to graduate. a. From the Empirical Rule, what is a range of values that 68% of the students should graduate between? to years   b. From the Emperical Rule, what is a range of values that 95% of the students should graduate between? to years

As you look intraorally, you notice that your patient has some mandibular crowding of the anterior teeth and that #8 and #9 are protruded. In this closed position, you start by examining the right molar relationship.  You find that the mesiobuccal cusp of the maxillary first molar is mesial to the mesiobuccal groove of the mandibular first molar by the width of a premolar.  You find that the 1st molar relationship is the same on the left side.   The occlusion would be classified as
