Question

Question: Create a third column above to make this a relative frequency distribution. Label the column “Percent” and calculate the values that go in that column.

Answer 1

Solution:

Given the table;

The percent column would be calculated using the formula;

$\frac{f}{\sum_^f}\times100$

Thus;

$\begin{gathered} \sum^f=33 \\ \\ 0-4\Rightarrow\frac{8}{33}\times100=24.24\text{ \%} \end{gathered}$$\begin{gathered} 5-9\Rightarrow\frac{2}{33}\times100=6.06\text{ \%} \\ \\ 10-14\Rightarrow\frac{5}{33}\times100=15.15\text{ \%} \\ \\ 15-19\Rightarrow\frac{7}{33}\times100=21.21\text{ \%} \\ \\ 20-24\Rightarrow\frac{4}{33}\times100=12.12\text{ \%} \\ \end{gathered}$$\begin{gathered} 25-29\Rightarrow\frac{6}{33}\times100=18.18\text{ \%} \\ \\ 30-34\Rightarrow\frac{0}{33}\times100=0\text{ \%} \\ \\ 35-39\Rightarrow\frac{1}{33}\times100=3.03\text{ \%} \end{gathered}$

Now, we can fill the third column as;
