Answer

Explanation:

Step1: Check scores in 66 - 71

Count scores in range. Only 71 is in 66 - 71, so frequency = 1.

Step2: Check scores in 72 - 77

Scores 77, 76, 73, 73, 75 are in range. Frequency = 5.

Step3: Check scores in 78 - 83

Score 80 is in range. Frequency = 1.

Step4: Check scores in 84 - 89

Scores 85, 89, 87, 89 are in range. Frequency = 4.

Answer:

Test score Frequency
66 to 71 1
72 to 77 5
78 to 83 1
84 to 89 4
