Answer :
Final answer:
To calculate the range of the snowfall data set, we subtract the minimum value (22.3 inches) from the maximum value (86.6 inches), resulting in a range of 64.3 inches.
Explanation:
The question involves calculating the range of a data set, which is a basic statistical concept in mathematics. The data set provided here represents the average winter snowfall in St. Paul, Minnesota over several years. To find the range, we must identify the maximum and minimum values of snowfall and subtract the smallest from the largest.
Following the data provided, we have these snowfall amounts in inches:
78.3, 32.0, 36.7, 32.4, 69.8, 67.7, 22.3, 86.6, 40.7, 45.0, 44.9, 35.5
The maximum snowfall is 86.6 inches, and the minimum is 22.3 inches. The range is calculated by subtracting the minimum from the maximum, like so:
Range = Maximum - Minimum
Range = 86.6 inches - 22.3 inches
Range = 64.3 inches
Therefore, the range of this data set is 64.3 inches.
