Question

Following are the lives in hours of 15 pieces of the components of aircraft engine. Find the median:

715, 724, 725, 710, 729, 745, 694, 699, 696, 712, 734, 728, 716, 705, 719.

Answer 1

Lives in hours of is pieces are

= 715, 724, 725, 710, 729, 745, 694, 699, 696, 712, 734, 728, 719, 705, 705, 719.

Arrange the above data in a sending order

694, 696, 699, 705, 710, 712, 715, 716, 719, 721, 725, 728, 729, 734, 745

N = 15(odd)

Median `=((N+1)/2)^(th)` term

`=((15+1)/2)^(th)`term

= 8^th term

= 716
