Need fast, being based on the data in the box plots, what is the best evidence to show which class has had greater success on field day over the last 10 years? mrs. cai’s class was more successful because her interquartile range was less spread out. mrs. cai’s class was more successful because she had the greater total spread. mr. roland’s class was more successful because his class always won at least one event. mr. roland’s class was more successful because his class’s lower quartile was the same as mrs. cai’s class’s upper quartile.

Mr. Roland’s class was more successful because his class’s lower quartile was the same as Mrs. Cai’s class’s upper quartile.

Step-by-step explanation:

From given scatter plot, we see that upper quartile of Mrs. Cai's class = 4

lower quartile of Mr. Roland’s class = 4

Both are equal so that means.

That means Mr. Roland’s class was more successful because his class’s lower quartile was the same as Mrs. Cai’s class’s upper quartile.

Hence last choice is correct.

d: Mr. Roland’s class was more successful because his class’s lower quartile was the same as Mrs. Cai’s class’s upper quartile.
