Answer :
Final answer:
The range of shoulder girth in the dataset is 54 cm, calculated by subtracting the minimum value (85 cm) from the maximum value (139 cm).
Explanation:
The range of shoulder girth in the dataset is the difference between the maximum and minimum values. To find the range, we simply subtract the minimum shoulder girth from the maximum shoulder girth.
Range = Maximum shoulder girth - Minimum shoulder girth
Range = 139 cm - 85 cm
Range = 54 cm
Therefore, the range of shoulder girth in the data set is 54 cm, which corresponds to option 3) 54.42 cm when considering two decimal places.
