Answer:

1) A. 54

2) D. 62

Step-by-step explanation:

Find the complete question in the attached diagram.

Range is the difference between the highest score and the lowest score.

Given the following scores on the Overcontrolled-Hostility scale.

69, 84, 56, 89, 47, 63, 86, 58, 74, 35, 71, 60

From the data:

Highest score = 89

Lowest score = 35

Range = Highest score - Lowest score

Range = 89-35

Range = 54

Hence the possible value of the range is 54

For the scores on the Defensiveness scale given as:

38, 70, 35, 42, 26, 87, 74, 61, 69, 46, 63, 25

Highest score = 87

Lowest score = 25

Range = Highest score - Lowest score

Range = 87-25

Range = 62

Hence the possible value of the range is 62
