error analysis a group of students is studying the number of left - handed people in their school. they surveyed everyone in their school. one of the students incorrectly said that the people they surveyed represents a sample because it only includes the people in their school. identify the population. what could cause the students error? what is the population the students are studying? a. everyone who is left - handed b. everyone in their school who is left - handed c. everyone in all schools d. everyone in their school
Answer
Brief Explanations:
The students are studying left - handed people in their school. The population is the entire group of interest for the study. Since the study is about left - handed people in their school, the population is everyone in their school who is left - handed. The student's error likely stems from a misunderstanding of the terms population and sample. A sample is a subset of the population, and in this case, if they surveyed everyone in the school who is left - handed, that is the entire population of interest for their study, not a sample.
Answer:
B. Everyone in their school who is left - handed
