Answer

Step 3: Substitute the values into the formula: \(Data\,Range = 30 - 5\)

Steps

Step 1 ：Step 1: Identify the smallest and the largest values in the data. In the given frequency distribution, the smallest value is 5 and the largest value is 30.

Step 2 ：Step 2: To find the data range, subtract the smallest value from the largest value. The formula to find the data range is: \(Data\,Range = Largest\,value - Smallest\,value\)

Step 3 ：Step 3: Substitute the values into the formula: \(Data\,Range = 30 - 5\)
