Note: You missed to add the dot plots chart. As I found the chart after a little research. Thus, I am attaching it and based on that dot plot chart I am solving the question which anyways would clear you concept.

Answer:

'There are about 2 more students in each class at Oak Middle School than at Poplar Middle School' is the correct statement.

Step-by-step explanation:

From the diagram, it is clear that

The data set containing Poplar Middle School:

20 20 20 21 21 21 21 21 22 22 22 22 22 22 22 23 23 23 23 24

The mean of a data set is the sum of the terms divided by the total number of terms. Using math notation we have:

$\mu = 435/20$

$=\frac{87}{4}$

$= 21.75$

The data set containing Oak Middle School:

20 21 21 22 22 23 23 23 23 24 24 24 25 25 26 26 27 27 28 29

The mean of a data set is the sum of the terms divided by the total number of terms. Using math notation we have:

$\mu = 483/20$

$=24.15$

So, the difference in mean will be:

$24.15 - 21.75 = 2.4$

Therefore, 'there are about 2 more students in each class at Oak Middle School than at Poplar Middle School' is the correct statement.
