Step-by-step explanation:
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:
The woman bought 2 items at $12 each.
Step-by-step explanation:
Given that a woman bought a number of items for $ 24, and she realized that if she had bought 4 more items for the same money, she would have paid $ 8 less per item, to determine how many Items did she buy the following calculation must be done:
X = 24
X + 4 = 24
24/2 = 12
24/6 = 4
12 - 4 = 8
Therefore, the woman bought 2 items.
Given
The graph of the infant mortality rate and life expectancy is given in the scatter form.
Explanation
To determine the relation between the life expectancy and infant mortality rate ,
use the given graph.
From the graph given, it is clear that as the infant mortality rate increases then the life expectancy decreases.
Therefore, the countries with high mortality rates tended to have shorter life expectancies.
Answer
Hence the correct option is B.
