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. Women have a noticeably higher percentage in the strictly voluntary category. There are not striking differences. Women dominate every category. Men 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.) Men Women Relative risk Write a clear sentences contrasting females and males using relative risk as your numerical summary. Men and Women partic

Explanation / Answer

The parts (a) and (c) have already been answered correctly. For part (b):

Proportion of men who volunteer = 33.9+3.6+7.1 = 44.6%

Proportion of women who volunteer = 44.6+1.4+5.1 = 51.1%

So, relative risk = 44.6/51.1 = 0.87
