I have the following question:

Questions 12 & 13, Fall 1998

You are given the following:

Losses follow a distribution (prior to the application of any deductible)
with cumulative distribution function and limited expected values as
follows:

Loss Size F(x) E[X;x]

10,000 0.60 6,000
15,000 0.70 7,700
22,500 0.80 9,500
infinity 1.00 20,000

There is a deductibleof 15,000 per loss and no policy limit

The insurer makes a nonzero payment p

Question 12

What is the expected value of p ?

Here, I used the mean residual formula and came up with $41,000. Does
anyone disagree?

Question 13

After several years of inflation, all losses have increased in size by 50%,
but the deductible has remained the same.

Determine the expected value of p.

This is where I am stuck.

I will appreciate it if anyone can help me out on this one.

Thanks.
