Question 2

The range of her scores is 120.

The range of her scores is determined by the difference between the highest and lowest scores achieved. In this case, the highest score minus the lowest score results in a range of 120.

A) 100

This option is incorrect as a score range of 100 does not represent the actual difference between the highest and lowest scores. The calculation shows that the actual range is greater than 100.

B) 120

This option is correct because it accurately reflects the range calculated from the scores provided. It represents the difference between the maximum and minimum scores achieved.

C) 440

This option is incorrect because a range of 440 is significantly higher than the calculated difference between the scores. This value does not align with the actual scores recorded.

D) 2,250

This option is incorrect as it is an excessively high range that does not correspond to the actual scores. The range should be significantly lower than this figure based on the provided data.

Conclusion

The correct answer, 120, is definitively right as it accurately represents the difference between the highest and lowest scores. All other options fail to reflect the correct calculation of the score range, demonstrating a misunderstanding of how to determine the range in this context.
