Question

a) About 3/4 scored higher; about 1/2 scored lower.
b) About 1/2 scored higher; about 1/2 scored lower.
c) About 3/4 scored higher; about 1/4 scored lower.
d) About 1/4 scored higher; about 3/4 scored lower.

Answer 1

In a box plot, if Christina's score is above the median, it means more than half of her classmates scored lower. If it is below the median, more than half scored higher.

Step-by-step explanation:

In the given scenario, Mrs. Oliver drew a box plot to represent her students' scores on a mid-term test. Christina earned 70 on the test. To describe how Christina's scores compare to her classmates, we need to analyze the box plot.

In the box plot, the median represents the middle score. If Christina's score of 70 falls below the median, it means that more than half of her classmates scored higher than her. On the other hand, if Christina's score is above the median, it means that more than half of her classmates scored lower than her.

Therefore, the correct option is (b): About 1/2 scored higher; about 1/2 scored lower.
