Question

A study examined patterns and characteristics of volunteer service for young people from high school through early adulthood. Here are some data that can be used to compare males and females on participation in unpaid volunteer service or community service and motivation for participation.

Note that the percents in each row sum to 100%.

(a) Graphically compare the volunteer-service profiles for men and women. Describe any differences that are striking.

There are no striking differences.Men dominate every category.    Women have a noticeably higher percentage in the strictly voluntary category.Women dominate every category.

(b) Find the proportion of men who volunteer. Do the same for women. Compute the relative risk of being a volunteer for females versus males. (Round your answer for relative risk to two decimal places.)

Write a clear sentence contrasting females and males using relative risk as your numerical summary.

Men and women participate equally.A higher percentage of women were participants.    A higher percentage of men were participants.none of the above

Participants Motivation Gender Strictly Voluntary Court-ordered Other Non-participants Men 32.0% 2.2% 5.8% 60.0% Women 43.4% 1.9% 6.6% 48.1%

Explanation / Answer

Solution:

The given information is related to the volunteer service for young people from high school through early adulthood.

a) The propotion men who volunteer is,
Proportion men volunteer = 1-Non Participants
= 1-0.60
= 0.40
Therefore, the proportion of men volunteers is 0.40

b) The propotion Women who volunteer is,
Proportion Women volunteer = 1- Non participants
= 1- 0.481
= 0.519
Therefore, the proportion of Women volunteer is 0.519

Compute relative risk of being a volunteer for females versus males
Relative risk = Proportion of women/ Proportion of men
= 0.519/0.40
= 1.2975
Therefore, the relative risk of being a volunteer for females versus men is 1.33
Men : 0.40
Women : 0.519
Relative risk : 1.2975

Gender Voluntary Count Ordered Other Non Participants Total Men 32.0 2.2 5.8 60.0 100 Women 43.4 1.9 6.6 48.1 100 Total 75.4 4.1 12.4 108.1 200
