Assignment # 10 - Calculate the appropriate life table functions using 
the Ascadi and Nemeskeri (1970) technique. 

         Observed % of              Prob. of Yrs livedTotal yrs  Life

10-14          21
15-19          44
20-24          26
25-29          28
30-34          42
35-39          42
40-44          19
45-49          19
50-54          12
55+            13
              680

Step 1 - Sum Dx.
Step 2 - Calculate percentage distribution of deaths by age.
Step 3 - Set radix of table at 100.
Step 4 - Calculate qx = dx / lx.
Step 5 - Calculate lx+n = lx -dx.
Step 6 L0 = .2 * l0 + .8* l 1-4
       L1-4 = .34* l0 + 1.184* l1-4 + 2.782* l5-9
       Lx = n/2 * (lx + lx+n)
Step 7 & 8 calculate Tx and ex as usual.
