Answer 1

Answer:

9.8%

Step-by-step explanation:

Given the following information

$\left|\begin{array}{c|cccccc}Ages &15-18&19-22&23-26&27-30&31-34&35-38\\ Number of students&6&4&5&7&10&9\end{array}\right|$

Total Number of Students =6+4+5+7+10+9=41

Number of Students aged 19-22 =4

Therefore:

The relative frequency for the class with a lower class limit of 19

$=\dfrac{4}{41}\times 100\\\\ =9.8\% (to one decimal place)$
