Explanation:

Step1: Analyze first option

From the table, total eleventh - graders are \(182 + 179=361
eq352\), so the first statement is false.

Step2: Analyze second option

Total tenth - graders are \(194 + 329 = 523\), and number of tenth - grade boys is \(329
eq173\), so the second statement is false.

Step3: Analyze third option

Total girls in the school are \(621\), and number of eleventh - grade girls is \(182\). So the third statement "Out of the 621 girls at the school, 182 of them are eleventh - graders" is true.

Answer:

Out of the 621 girls at the school, 182 of them are eleventh - graders.
