#### Answer

mean: 18.46 in median: 20.41 in mode: 20.41 in range: 13.188 in

#### Work Step by Step

$6.5, 3.2, 7.4, 6.5, 5.8$ mode = most often 6.5 appears twice $6.5*\pi = 20.41$ median =middle $6.5, 3.2, 7.4, 6.5, 5.8$ $3.2, 5.8, 6.5, 6.5, 7.4$ $5.8, 6.5, 6.5$ $6.5$ $6.5*\pi = 20.41$ range = max - min range = 7.4 - 3.2 range = 4.2 $4.2 *\pi = 13.188$ mean = average $3.2, 5.8, 6.5, 6.5, 7.4$ $(3.2+5.8+6.5+6.5+7.4)/5$ $29.4/5 = 5.88$ $5.88*\pi = 18.4632$
