Question

select the correct answer. which data set has the greatest spread? set a - {84, 91, 87, 77, 94, 89, 74} set b - {89, 73, 84, 91, 87, 77, 94} set c - {73, 84, 89, 88, 77, 91, 87, 90} set d - {84, 89, 88, 82, 91, 87, 99} a. set a b. set b c. set c d. set d

Explanation:

Step1: Find range for Set A

Range = Max - Min. For Set A = {84, 91, 87, 77, 94, 89, 74}, Max = 94, Min = 74. Range = 94 - 74 = 20.

Step2: Find range for Set B

For Set B = {89, 73, 84, 91, 87, 77, 94}, Max = 94, Min = 73. Range = 94 - 73 = 21.

Step3: Find range for Set C

For Set C = {73, 84, 89, 88, 77, 91, 87, 90}, Max = 91, Min = 73. Range = 91 - 73 = 18.

Step4: Find range for Set D

For Set D = {84, 89, 88, 82, 91, 87, 99}, Max = 99, Min = 82. Range = 99 - 82 = 17.

Answer:

B. Set B
