The amounts of money requested in home loan applications at the federal savings are approximately normally distributed with a mean of $70000 and a standard deviation of $20000. a loan application is received. what is the probability that:
\n" ); document.write( "1. the amount requested is $80 000 or more
\n" ); document.write( "1 have tried to work the first question
\n" ); document.write( "z(80000) = (80000 - 70000) / 20000 = 0.5
\n" ); document.write( "----
\n" ); document.write( "P(x >= 80000) = P(z>= 0.5) = 0.3085
\n" ); document.write( "---------------------------------------------
\n" ); document.write( "2. twenty percent of the loans are larger than what amount
\n" ); document.write( "Find the z-value with a left tail of 80%
\n" ); document.write( "invNorm(0.8) = 0.8416
\n" ); document.write( "---
\n" ); document.write( "Find the corresponding loan value using x = zs+u
\n" ); document.write( "x = 0.8416*20000+70000 = $86832.42
\n" ); document.write( "==========
