A veterinary scientist is interested in investigating the (potential) effect of weaning time on the severity of infection of gastrointestinal nematode (GIN) parasites among all calves at a large farm. Thirty-six (36) pregnant cows were randomly selected from all cows pregnant with a single calf at this farm. Note that approximately 90% of cow pregnancies at this farm are singleton pregnancies. The calves of these cows were randomly assigned to two different weaning times: 16 weeks and 24 weeks. Once each calf was born, the calf and its mother were moved to a pasture with a known presence of nematodes to graze. The calf was then weaned at its assigned weaning time by moving it to an adjacent pasture (with the same nematode activity as the first pasture) to graze. Once each calf reached the age of eight months, the FEC was measured in eggs per gram (egg/g). a. What is the population of interest in this study? Be specific. b. What is the sample in this study? Be specific. c. Is the sample representative of the population in this study? Justify your answer. d. What is the variable of interest in this study? e. Is the variable of interest you identified quantitative or qualitative? f. Is this study a designed experiment or observational study? Justify your answer.
