Algebra.Com's Answer #114391 by stanbon(75887) ![]() You can put this solution on YOUR website! The average hourly wage of employees of a certain company is $9.83. Assume the variable is normally distributed. If the standard deviation is $4.58, find the probability that a randomly selected employee earns less than $5.43. \n" ); document.write( "------------------- \n" ); document.write( "Find the z-score of 5.43 \n" ); document.write( "z(5.43) = (5.43-9.83)/4.58 = -0.960699 \n" ); document.write( "------- \n" ); document.write( "Then P(x < 5.43) = P(z < -0.960699) = 0.1684 = 16.84% \n" ); document.write( "====================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "================= \n" ); document.write( "0.313 = 31.3% \n" ); document.write( "0.168 = 16.8% \n" ); document.write( "0.436 = 43.6% \n" ); document.write( "0.345 = 34.5% \n" ); document.write( " \n" ); document.write( " |
