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. Participants Motivation Gender Strictly voluntary Court-ordered other Non-participants Men 34.0% 2.8% 6.4% 56.8% Women 42.9% 1.0% 7.5% 48.6% 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. Women dominate every category. Women have a noticeably higher percentage in the strictly voluntary 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 W

Explanation / Answer

(a)

c. Womens have a noticeably higher percentage in the strictly voluntary category.

(b)

Men = 34.03% + 2.8% + 6.4%

Men = 0.3403 + 0.028 + 0.064 = 0.4323

Women = 0.429 + 0.01 + 0.075 = 0.514

Realative risk = proportion of Female volunteer / proportion of male volunteer

Relative risk = 0.514 / 0.4323 = 1.19

Mean = 0.4323

Famale = 0.514

Relative risk = 1.19
