Question

Help me :))))) it’s a study guide.

Answer 1

Answer:B. Her mean, median and mode are equal.

Step-by-step explanation:

Mean = (sum of the outcomes)/(total number of outcomes)

Total number of rounds played is 7

The scores for the 7 rounds played are - 6, - 4, - 1 , +3 , - 2, -1, +4

Sum of the scores = - 6 - 4 - 1 + 3 - 2 -1 + 4 = -7

Mean = - 7/7 = - 1

The mode is the most occurring score. Looking at the scores, - 1 occurred twice, so the mode is - 1

The median is the middle score. We would determine it by rearranging the scores in increasing or decreasing order. It becomes

- 6, - 4, - 2, -1, -1, +3, +4

The median is -1

The true statement is

B. Her mean, median and mode are equal.
