Studdy Solution
Determine whether the survey scenario represents a random sample, a census, or neither.
The scenario describes giving a survey to all 850 students at Jackson Middle School. Since every student is surveyed, this is an example of a census, and the results will provide parameters about the population. Therefore, the correct answer is: B. This is an example of a census and the results will provide parameters about the population.
Solution Summary:
15. The data is categorical.
16. The proportion of principals in the sample with children under the age of 8 is 0.74.
17. The description that best describes the population is D. All Minnesota school principals.
18. The statement that is true about the survey scenario is B. This is an example of a census and the results will provide parameters about the population.
