Solution

Lives in hours of is pieces are $=$ $714, 724, 725, 710, 729, 745, 694, 699, 696, 712, 734, 728, 716, 705, 719$
Arrange the above data in ascending order $=$ $694, 696, 699, 705, 710, 712, 715, 716, 719, 721, 725, 728, 729, 734, 745$
$N = 15 (o d d)$
Medium $= {(\frac{N + 1}{2})}^{t h} t e r m s$
$= {(\frac{15 + 1}{2})}^{t h} t e r m s = 8^{t h} t e r m s = 716$
