Question 442252
About 42% 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 134 insurance claims to be processed in the next few days. Find the following probabilities. (Round your answers to four decimal places.) 
(a) half or more of the claims have been padded
P(67<= x <=134) = 1-binomcdf(134,0.42,66) = 0.0374
-----------------------------
1 
(b) fewer than 45 of the claims have been padded
binomcdf(134,0.42,44) = 0.0187
-----------------------------------------
2 
(c) from 40 to 64 of the claims have been padded
binomcdf(134,0.42,64)- binomcdf(134,0.42,39) = 0.9229
-------------------------------------------------
3 
(d) more than 80 of the claims have not been padded
1 - binomcdf(134,0.58,79) = 0.3794
=====================================
