a) What is the population of interest? Approximately, how many people are in the population ofinterest? (Recall, the definition of a population is: The collection of all outcomes, responses, measurements,or counts that are of interest.)b) What is the best data collection method to use for the study (explain)? (Recall, data collectionmethods are: Observation, Survey, Experiment, Simulation).c) For one of the three studies, a census is possible. Determine which one and then explain why a censusis possible for that study and is not possible for the other two studies, (A census means that we are ableto collect data from every unit in the population. Most of the time the population is too large for a censusto be feasible)d) For the two studies where a census is not possible, how many people, students, or cars would yousample out of the population? What sampling technique would you use (see section 1.3)? (Explain vourreasoning)Replies: Reply to at least two classmates. Your replies should address the following:a) Your first reply should address the correctness of a classmate's answer for part a and whether yousupport their decision in part b.b) Your second reply should address a classmate's answer to part c and d. Provide an alternativesampling strategy, with justification.See the syllabus for complete grading information.

1. A. For study 1, the population of interest are the people of South Carolina. As Col of 2020, the population of South Carolina was 5.092 million. However we are only interested in people who have high blood pressure and/or people who consume a lot of salt. 1. B. For study 1, we should split the sample into two different groups. During a time period, one group will consume a lot of salt, while the other group does not. We will then check their blood pressure levels and see if there is a difference be- tween the two groups. We will be using observation to watch the levels of salt and the blood pressure. 1. C. Census is not possible for this study because the amount of people with high blood pressure in the state of South Carolina is too large. 1. D. Stratified sampling can be used because we need to expect the interest cal- culation to be different between different groups and subgroups. This includes sex and age. I would sample all of the people in South Carolina that have high blood pressure. 2. A. For study 2, the interesting population is the number of students at enrolled at GMC. for 2019-2020, the number of students enrolled at GMC were about 16,000. 2. B. I would use surveys and questionaries to collect the data because it will help us get an accurate answer from each student and how many hours they work a week. 2 Census is possible because we can distribute surveys and questionaries to
