Answer 1

Answer:

range=22-2=2

coefficient of range =2/22+2 =1/12

hope you got the answer.

please mark me as branliest

Answer 2

Answer:

20 is the range

0.833 is the coefficient of range

Step-by-step explanation:

Take the largest number and subtract the smallest number from it to find range:

    22 - 2 = 20

To find the coefficient of range:

    (Largest Number - Smallest Number)/(Largest Number + Smallest Number)

Plug in these values, like so:

    (22 - 2)/(22 + 2) = 0.833
