X is a normally distributed random variable with a mean of 22 and a standard deviation of 5. The probability that X is less than 9.7 is ?
\n" ); document.write( "----------
\n" ); document.write( "z(9.7) = (9.7-22)/5 = -2.46
\n" ); document.write( "-------
\n" ); document.write( "P(x < 9.7) = P(z < -2.46) = 0.0069
