Need fast, being ! the box plot compares the number of events that mrs. cai’s and mr. roland’s classes won over the last 10 years on the school’s field day. 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.

The best evidence to show which class has had greater success on field day over the last 10 years is ''Mr. Roland’s class was more successful because his class’s lower quartile was the same as Mrs. Cai’s class’s upper quartile''.

Given

The box plot compares the number of events that Mrs. Cai’s and Mr. Roland’s classes won over the last 10 years on the school’s field day.

The upper quartile is the median of the upper half of the data points.

The lower quartile is the median of the lower half of the data points.

From the given the value of the upper quartile of Mrs. Cai's class = 4 and the lower quartile of Mr. Roland’s class = 4.

So, Mrs. Cai's class's box ranges from 2 to 4, that is, her class’s upper quartile is 4.

Mr. Roland's class's box ranges from 4 to 7, that is, his class’s lower quartile 4.

Hence, the best evidence to show which class has had greater success on field day over the last 10 years is ''Mr. Roland’s class was more successful because his class’s lower quartile was the same as Mrs. Cai’s class’s upper quartile''.

Last choice "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.

" is correct.

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.
