Answer 2

SOLUTION

TO DETERMINE

The range and co-efficient range

3, 7, 21, 24, 37, 40, 45

CONCEPT TO BE IMPLEMENTED

For a given set of observations

1. Range = Maximum value - Minimum Value

2. The coefficient of Range

$= \displaystyle \sf{ \frac{Maximum \: value - Minimum \: Value}{Maximum \: value + Minimum \: Value} }$

EVALUATION

CALCULATION OF RANGE

Here the given set of observations are

3, 7, 21, 24, 37, 40, 45

Maximum value = 45

Minimum value = 3

∴ Range

= Maximum value - Minimum Value

= 45 - 3

= 42

∴ Range = 42

CALCULATION OF COEFFICIENT OF RANGE

The coefficient of Range

$= \displaystyle \sf{ \frac{Maximum \: value - Minimum \: Value}{Maximum \: value + Minimum \: Value} }$

$= \displaystyle \sf{ \frac{45 - 3}{45 + 3} }$

$= \displaystyle \sf{ \frac{42}{48} }$

$= \displaystyle \sf{ \frac{7}{8} }$

= 0.875
