#### Answer

mean = 229.7 median = 144 mode = 96 and 300 range = 528

#### Work Step by Step

$6, 8, 25, 8, 12, 50, 25$ $6, 8, 8, 12, 25, 25, 50$ mode = most often 8 and 25 appear twice, so both are the mode $8* 12= 96$ $25*12 = 300$ mean = average $6, 8, 8, 12, 25, 25, 50$ $(6+8+8+12+25+25+50)/7$ $134/7$ (feet) $134*12/7$ (inches) $229.7 inches median =middle$6, 8, 8, 12, 25, 25, 508, 8, 12, 25, 258, 12, 251212*12= 144$range = max - min range =$50-6\$ range = 44 range = 44*12 range = 528
