In the Oppliger et al. (1996) dataset, 7 out of 35 birds in the control group were found to be infected with avian malaria.Calculate a point estimate and 95% confidence interval for the background prevalence of malaria in this population (prevalence is the proportion of a population that has a disease).

I honest don't know if i should isolate the control group and the infected population out or I will have to do it as a whole.

BTW, I have never used bbmle package in this class that is required for this question before so I get even more confused
