Explanation:

Step1: Recall the formula for range

The range of a data - set is calculated as \(Range = Maximum\ value - Minimum\ value\).

Step2: Identify the maximum and minimum values from the dot - plot

From the dot - plot of quiz scores, the minimum value \(Min = 60\) and the maximum value \(Max=100\).

Step3: Calculate the range

Substitute the values into the range formula: \(Range=100 - 60\).

Answer:

\(40\)
