The statement that correctly compares the students’ test scores is that the median of Jen's score is greater than the median of Ron's score.
<h3>How to find mean and median?</h3>
Jen and Ron each took five tests. There test score are as follow:
- Jen: {45, 91, 84, 66, 74}
- Ron: {70, 95, 99, 69, 72}
Let's find the mean and median of the test score to compare them correctly
Jen: {45, 66, 74, 84, 91}
mean of Jen score = 45 + 66 + 74 + 84 + 91 / 5
mean of Jen score= 360 / 5
mean of Jen score = 72
Median of Jen score = 74
Ron: {69, 70, 72, 95, 99}
mean of Ron score = 69 + 70 + 72 + 95 + 99 / 5
mean of Ron score = 405 / 5
mean of Ron score = 81
median of Ron score = 72
Therefore, the median of Jen's score is greater than the median of Ron's score.

Answer:
A. DEF=EDF
Step-by-step explanation:
Step-by-step Answer:
The coordinates of the mid-point of a segment whose end-points are known is the average of the coordinates of the end-points.
Here, the end-points are: (-11,0), (9,-1)
So the x-coordinate of the mid-point is (-11+9)/2 = (-2/2) = -1, and
the y-coordinate of the mid-point is (0-1)/2 = -0.5
So the mid-point is (-1,-0.5)
