MATH 471: Actuarial Theory I Homework #5: Fall 2010 Assigned September 22, due September 29 1. Mortality follows the select-and-ultimate life table: x l [ x ] l [ x ]+ 1 l x + 2 x + 2 30 9,906 9,904 9,901 32 31 9,902 9,900 9,897 33 32 9,898 9,896 9,892 34 33 9,894 9,891 9,887 35 34 9,889 9,886 9,882 36 Calculate 1 | q [30] . ( 0.0003028 ) 2. A select-and-ultimate life table with a select period of 2 years is based on probabilities that satisfy the following relationship: q [ x - i ]+ i = 2 4 - i × q x for i = 0, 1. You are given that l 68 = 10,000, q 66 = 0.026, and q 67 = 0.028. Calculate: (a) l 67 . ( 10,288.07 ) (b) l [65]+1 . ( 10,469.53 ) 3. You are given: (i) x l [ x ] l [ x ]+ 1 l x + 2 x + 2 65 8,200 67 66 8,000 68 67 7,700 69 (ii) 3 q [ x ]+1 = 4 q [ x +1] (iii) 4 q x +2 = 5 q [ x +1]+1 Calculate l [67] .
