Consider the following (illustrative) life table
Age lx
0. 100
- 85
- 75
- 50
- 45
- 30
- 57
- 0
Calculate the median lifetime and the
expected remaining lifetime of a life aged 2 for this population.
Homework Answers
The lifetimes sorted in ascending order are:
0
30
45
50
57
75
85
Total number of observations(n)=7
Since n is odd, median is (n+1)/2th observation
= (7+1)/2th observation
=8/2th observation
=4th observation
=50 years
So median lifetime is 50 years.
Average lifetime=(0+30+45+50+57+75+85)/7
=342/7
=48.85 which can be rounded to 49
So expected remaining lifetime of a life aged 2 for this population is 49-2=47 years
