Algebra.Com's Answer #792705 by Boreal(15235) You can put this solution on YOUR website! z=(x-mean)/sd \n" ); document.write( ">(70-68)/5=2/5 \n" ); document.write( "probability z>(2/5) or 0.4 is 0.3446 \n" ); document.write( "- \n" ); document.write( "fewer than 64 inches is a z=(64-68)/5 or -4/5 or -0.8 \n" ); document.write( "that probability is 0.2119, what you got for 6. It belongs here. \n" ); document.write( "- \n" ); document.write( "z=0. The probability z>0 is 50% \n" ); document.write( "The probability z <0 is 50% \n" ); document.write( "The probability z=0 is 0. \n" ); document.write( " |
