Question 411409
Do you try to pad an insurance claim to cover your deductible? About 40% of all U.S. adults will try to pad their insurance claims! Suppose that you are the director of an insurance adjustment office. Your office has just received 128 insurance claims to be processed in the next few days. 
---
Binomial with n = 128 and p = 0.4
===
What is the probability that: 
(a) Half or more of the claims have been padded?
P(x >= 61) = 1 - binomcdf(128,0.4,60) = 0.0475
Used TI-84 calculator.
-------------------------------- 
(b) 44 or less of the claims have been padded?
binomcdf(128,0.4,44) = 0.1127
-------------------------------- 
(c) From 40 to 64 of the claims have been padded?
binomcdf(128,0.4,64)-binomcdf(128,0.4,39) = 0.9751
