Final answer:
The range of the student scores is 70.
Step-by-step explanation:
The range of a set of numbers is the difference between the maximum and minimum values in the set. To find the range of the student scores, we first arrange the scores in ascending order:
10, 30, 30, 60, 80
The minimum score is 10 and the maximum score is 80. Subtracting the minimum from the maximum, we get:
Range = 80 - 10 = 70
Therefore, the range of the student scores is 70.
