2. Go back to the file GSB 519 Male Survivors found under Content, Week 2 in D2L. Let x denote age, let lx denote the number of people alive at age X in the Male 1 _ X+i px' _ Survivors life table, and j I, denotes the probability of still being alive j years E after age X. Life expectancyL X at age x is LEX ='5+ px1+ pr + px3 +H' until the end of the life table. That is, life expectancy LE, at age x is the sum of the probabilities of surviving additional years beyond age x until you reach the end of the life table plus .5 of a year (to center deaths between years at the mid points of years). Expected age at death for a person currently age x is the sum of x and life expectancy at age X. That is, expected age at death for a person currently age X is X+LEX Create an Excel spreadsheet which computes life expectancies at ages x = 0, 20, 40, 60, 80 and the corresponding expected ages at death for these ages. Copy and paste your Excel work into a Word file in the detailed work part of the assignment
