document.write( "Question 869862: Use the standard normal table to determine the probability. The distribution of cholesterol levels in teenage boys is approximately normal, with µ = 170 and σ = 30. Levels above 200 warrant attention. If 95 teenage boys are examined, how many would you expect to have cholesterol levels greater than 225?

 µ = 170 and σ = 30
\n" ); document.write( "P(x > 225): z = (225-170)/(30/sqrt(95)) = 55/3.0779= 17.869
\n" ); document.write( "P(z > 17.869 ) = ~0
\n" ); document.write( " basically NO teenage boy would be expected to have cholesterol levels greater than 225
