The height of 11 men were 61, 64, 68, 69, 67, 68, 66, 70, 65, 67 and 72 inches. Calculate the range If the shortest man is omitted, what is the percentage change in the range?

Answer»

1. Range = L = S = 72 – 61 = 11 inches.

2. New Range (Shortest man is omitted)

= L – S = 72 – 64 = 8

change in range =11 – 8 = 3 inches

Percentage change in range = 3/11 x 100 = 27.2%
