Table 2.1 lists the number of freshmen students and the overall enrollment of the Schools of Engineering, Computer Science and Statistics of University of Roma “La Sapienza” over eight academic years. Note that the overallnumbersinTable2.1comprisesbothundergraduateandgraduatelevelstu-dents.A student that fulfills the undergraduate degree will move to graduate level courses with probability = 0.7. Reports say that students completing both degrees (bachelor’s and master’s) take 7.5 years on the average.

Could you give an estimate of the average time that students take to achieve a bachelor’s degree and the average time it takes to obtain amaster’s degree?
