Algebra.Com's Answer #768484 by Boreal(15235) You can put this solution on YOUR website! Yes, that's how you do it. \n" ); document.write( "The z score for the value of 130 in the original distribution is 7/8 \n" ); document.write( "Therefore, that has to be the z-score of the new value in the second distribution. \n" ); document.write( "Since the z-score is (x-mean)/sd you get the result you got. \n" ); document.write( " \n" ); document.write( " |
