The following two-way table shows the places where high school students have volunteered in the past month. The table will be converted into a relative frequency table. Which value is the joint relative frequency of the number of 10th grade students who volunteered at the animal shelter?

9th Grade 10th Grade 11th Grade 12th Grade Total
Animal Shelter 6 8 4 10 28
Hospital 12 17 13 19 61
Library 5 6 4 7 22
Boys and Girls Club 9 14 15 11 49
Total 32 45 36 47 160

Using the two way table in presenting the given data, we could then say that the number of 10th grader who volunteer themselves in animal shelter is 0.05. Thsi is computed by identifying first then of participant that is 10th grader and is on animal shelter volunteering, in this case it is 8. Then it will be divided by the total number of participant which is 160.

The joint relative frequency of the number of 10th-grade students who volunteered at the animal shelter is 0.05.

How to find the relative frequency?

Relative frequency is the ratio of the considered sub-group's count to the total count. (so its frequency of the considered subgroup relative to the total frequency).

The following two-way table shows the places where high school students have volunteered in the past month.

The table will be converted into a relative frequency table.

The 10th grader on animal shelter volunteering is 8.

The total number of participant is 160.

Relative frequency = 8 / 160

= 0.05

Hence, The number of 10th graders who volunteer themselves in an animal shelter is 0.05.
