Number of steps in Monday = 8565 steps

Number of steps in Tuesday = 14707 steps

Number of steps in Wednesday = 15323 steps

Number of steps in Thursday = 9788 steps

Number of steps in Friday = 12482 steps

Formula for range = Highest value – Lowest value

Here, highest value = 15323 and lowest value = 8565

Range of the number of steps = 15323 – 8565 = 6758

Hence, range of the number of steps is 6758 steps.
