Please answer it right (NO spam) I will give Brilliant Imagine you have any study(any study), you must assume one.

For this study you assumed, determine the following:

1. Say what the study is.

2. Determine the population of your study.

3. What it is universe type (finite/infinite?)

4. Determine the sampling unit.

5. Determine the sample size (only assume any number provided that ≤ ).

6. Determine what the population parameter(s) you want to estimate.

7. Assume any number of budgetary constraints for your study.

Jeffery conducted a survey in his school and found that 30 of the 50 eighth grade students' favorite subject is mathematics. based on the results, jeffery concluded that out of the 200 students in his school, 120 students' favorite subject is mathematics. select the statement that is true about jeffery's conclusion. a. jeffery's conclusion is not valid because the sample was biased since only 200 students were surveyed. b. jeffery's conclusion is valid because the sample was random since all of the students were eighth grade students. c. jeffery's conclusion is valid because the sample was random. d. jeffery's conclusion is not valid because the sample was biased since all of the students were eighth grade students.

Determine whether the points (–3,–6) and (2,–8) are in the solution set of the system of inequalities below. x ? –3 y < 5? 3x + 2 a. the point (–3,–6) is not in the solution set, and the point (2,–8) is in the solution set. b. neither of the points is in the solution set. c. the point (–3,–6) is in the solution set, and the point (2,–8) is not in the solution set. d. both points are in the solution set.
