Answer: Third option: <span>the percentage of students who earned a score of “needs improvement” on the Chapter 6 test and a score of “proficient” on the Chapter 7 test.
</span>
3 represents the number of <span>of students who earned a score of “needs improvement” on the Chapter 6 test.
16=3+13 represents the number total </span><span>of students who earned a score of “proficient” on the Chapter 7 test.
Then 3/16=0.1875=0.1875*100%=18.75% represents </span>the percentage of students who earned a score of “needs improvement” on the Chapter 6 test and a score of “proficient” on the Chapter 7 test.
