1. A population of raccoons (N = 10), all 10 raccoons have 2 sexual partners. What is the variance/mean ratio of this population?

2. In the same population of raccoons (N = 10) in which all 10 raccoons have 2 sexual partners, the mortality/recovery rate = 1, and the transmission coefficient = 0.5, What is the basic reproductive rate?

3. A different population of raccoons (N = 20) have the following number of sexual partners.

8 raccoons have 1 sexual partner

11 raccoons have 2 sexual partners

1 raccoon has 10 sexual partners

What is the variance to mean ratio of the distribution of sexual partners in this population?
