Answer: k = 11%
Step-by-step explanation:
The relative frequency fr is calculated by dividing the frequency xi of a given Class by the number of total data.
[tex]fr = \frac{xi}{n} * 100\%[/tex]
In this problem there are 4 Class U ^ V and S ^ T
Notice in the first table that the total number of data is n = 19.
The relative frequency of k will be the frequency of T ^ V between the total number of data.
Notice in the first table that the frequency of the Class T ^ V is 2.
So
[tex]k = \frac{2}{19} * 100\%\\\\k = 11\%[/tex]
