Question

question: 1. two sets of data are given. set a: 18, - 7, 16, 3, - 2, 9. set b: 5, - 4, 6, 1, 12. what is the difference between the range of set a and the range of set b?

Explanation:

Step1: Find range of Set A

Range = Maximum - Minimum. For Set A: 18, - 7, 16, 3, - 2, 9, the maximum is 18 and the minimum is - 7. So range of Set A = 18-(-7)=25.

Step2: Find range of Set B

For Set B: 5, - 4, 6, 1, 12, the maximum is 12 and the minimum is - 4. So range of Set B = 12 - (-4)=16.

Step3: Find difference of ranges

Difference = Range of Set A - Range of Set B = 25 - 16 = 9.

Answer:
