Transcribed Image Text:
For a group of 500 lives, each age 65, with independent future lifetimes, you are given:
Each life is to be paid 5 per month at the beginning of each month, if alive.
To fund these payments, each life will contribute an amount of c to a fund to support
these payments. This contribution is to be made immediately today and only once.
Y is the present value random variable today of total annuity payments to the 500 lives.
(12) = 0.12
(12)
A = 0.1196
2(12) 0.0395
165
The 95th percentile of a standard normal distribution is 1.645.
Using the normal approximation, calculate c such that Pr[500c > Y] = 0.95.
