The numbers of miles Ron biked are 31, 35, 49, 32, 45, 29, 33, 28, and 40.
Determine the range of this data set. (1 point)
• 9 miles
• 35.8 miles
• 21 miles
• 18 miles
The range of a data set is calculated by subtracting the smallest value from the largest value.
In this case, the smallest value 28 (by sorting the numbers in ascending order) and the largest value is 49.
Therefore, the range is 49 - 28 = 21 miles.
So, the correct answer is:
• 21 miles
