In the past, 60 % of all undergraduate students enrolled at state university earned their degrees within four years of matriculation. a random sample of 95 students from the class that matriculated in the fall of 2012 was recently selected to test whether there has been a change in the proportion of students who graduate within four years. Administrators found that 40 of these 95 students graduated in the spring of 2016 (i,e. , four academic years after matriculation) ....
