I have the answer to this problem and I am sure I am using the correct formula, but I am not getting the correct answer of .227
\n" ); document.write( "The lifetime of a machine component is normally distributed with a mean of 3 and a standard deviation of .16. What is the probability that X is greater than 3.3
\n" ); document.write( "X ~ N(3, .16)
\n" ); document.write( "-------------
\n" ); document.write( "z(3.3) = (3.3-3)/0.16 = 1.875
\n" ); document.write( "---
\n" ); document.write( "P(x > 3.3) = P(z > 1.875) = 0.0304
\n" ); document.write( "------
