The net worth of senior citizens is normally distributed with mean equal to $225,000 and standard deviation equal to $35,000. What is the probability that a single randomly selected senior citizen will have a net worth less than $300,000
\n" ); document.write( "-------
\n" ); document.write( "z(300,000) = (300,000-225000)/35000 = 75/35 = 2.1429
\n" ); document.write( "---
\n" ); document.write( "P(x > 300,000) = P(z > 2.1429) = 0.0161
