Algebra.Com's Answer #133608 by Mathtut(3670)![]() ![]() ![]() You can put this solution on YOUR website! a) mean (13.5+15+13.5+11+13)/5(terms)=66/5=13.2 is the mean \n" ); document.write( ": \n" ); document.write( "median of {11,13,13.5,13.5,15} is 13.5 the middle value \n" ); document.write( ": \n" ); document.write( "mode is also 13.5 as it is the number repeated most often \n" ); document.write( ": \n" ); document.write( "b) 32, 28.3, 26.8, 31, 24.4 \n" ); document.write( "re write in ascending order to {24.4,26.8,28.3,31,32} \n" ); document.write( ": \n" ); document.write( "mean 24.4+26.8+28.3+31+32/5(terms)=142.5/5=28.5 \n" ); document.write( ": \n" ); document.write( "median is 28.3 the middle term \n" ); document.write( ": \n" ); document.write( "mode is: If all the numbers appear only once, then there is no mode. Therefore there is no mode in this problem\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
