Suppose we wish to characterize the distribution of birth weights of all live birth infants that were born in Metro Manila in 2000. Assume that underlying distribution of birth weight has an expected value and variance. Ideally, we wish to estimate mean and variance exactly, based on the entire population of Filipino live born infants in 2000. But this is impossible with such a large group. A certain heart study seeks to accurately assess the prevalence and incidence of different types of cardiovascular morbidity in the province of Batangas, as well as trends in these rates over time. It is impossible to survey every individual to state. It is also impractical to survey in person, a random sample of individual in the province, since it requires a large number of interviewers to be dispersed throughout the province. The nurses' health study is a large epidemiology study involving 1,000 female nurses in different provinces. The nurses were first contacted by mail in 1996 and

I. Identify the type of sampling to be used in each of the following. Suppose we wish to characterize the distribution of birth weights of all live birth infants that were born in Metro Manila in 2000. Assume that underlying distribution of birth weight has an expected value and variance. Ideally, we wish to estimate mean and variance exactly, based on the entire population of Filipino live born infants in 2000. But this is impossible with such a large group. 1. A certain heart study seeks to accurately assess the prevalence and incidence of different types of cardiovascular morbidity in the province of Batangas, as well as trends in these rates over time. It is impossible to survey every individual to state. It is also impractical to survey in person, a random sample of individual in the province, since it requires a large number of interviewers to be dispersed throughout the province. 2. The nurses' health study is a large epidemiology study involving 1,000 female nurses in different provinces. The nurses were first contacted by mail in 1996 and they have been traced every 2 years by mail since then. Suppose we want to select a test sample of 100 nurses to test a new procedure for obtaining serum samples by 3. mail.
