Answer 2

Range is 63.7

Co-efficient of Range (CR) is 0.966

Explanation:

The formula for computing the range is as:

Range = Highest - Lowest

where

Highest = 90% of 72

= 64.8

Lowest = 10% of 11

= 1.1

So, putting the values above:

Range = 64.8 - 1.1

Range = 63.7

The formula for computing the Co-efficient of Range (CR) as:

Co-efficient of Range (CR) = Highest - Lowest / Highest + Lowest

So,

Highest is 64.8

Lowest is 1.1

Putting the values above:

CR = 64.8 - 1.1 / 64.8 + 1.1

CR = 63.7 / 65.9

CR = 0.966
