(c) An epidemiologist is worried about the ever increasing trend of malaria in a certain locality  and wants to estimate the proportion of people infected in the peak malaria transmission  period. If he takes a random sample of 150 people in that locality during the peak  transmission period and finds that 60 of them are positive for malaria, find  i. 99% confidence interval for the proportion of the whole infected people in that  locality during the peak malaria transmission period.
