Step-by-step explanation:
Solution :
L - 125 and S = 63
Range = L - S
= 125 - 63
Range = L - S = 62
Coefficient of range = (L - S)/(L + S)
L + S = 125 + 63 = 188
Coefficient of range = 62/188
= 31/94
= 0.33
(ii) 43.5, 13.6, 18.9, 38.4, 61.4, 29.8
L - 61.4 and S = 13.6
Range = L - S
= 61.4 - 13.6
Range = L - S = 47.8
Coefficient of range = (L - S)/(L + S)
L + S = 61.4 + 13.6 = 75
Coefficient of range = 47.8/75
= 478/750
= 0.64
