Arada [10]

Answer:

<u>Range = 1 1/4</u>

Step-by-step explanation:

Range = Maximum - Minimum

Arranging the data in ascending order :

  • <u>1/2, 5/8, 3/4, 1 1/4, 1 1/2, 1 3/4</u>

<u />

Solving for range :

  • Range = 1 3/4 - 1/2
  • Range = 1 3/4 - 2/4
  • Range = 7/4 - 2/4
  • Range = 5/4
  • <u>Range = 1 1/4</u>
