practice 2b score: 13.99/46 answered: 11/23 question 12 ages number of students 15 - 18 5 19 - 22 9 23 - 26 10 27 - 30 7 31 - 34 5 35 - 38 8 based on the frequency distribution above, find the relative frequency for the class with lower class limit 35 relative frequency = % give your answer as a percent, rounded to one decimal place question help: video submit question

Explanation:

Step1: Calculate total number of students

$5 + 9+10 + 7+5 + 8=44$

Step2: Identify frequency of the class 35 - 38

The frequency of the class with lower - class limit 35 (i.e., 35 - 38) is 8.

Step3: Calculate relative frequency

The formula for relative frequency is $\text{Relative Frequency}=\frac{\text{Frequency of the class}}{\text{Total frequency}}\times100\%$. So, $\text{Relative Frequency}=\frac{8}{44}\times100\%$.
$\frac{8}{44}\times100\%=\frac{800}{44}\% \approx 18.2\%$

Answer:

$18.2$
