Question 1.

In a recent published poll of 200 students at a midwestern university, 150, or 75%, said they would try to purchase used textbooks before buying new textbooks. The report stated that somewhere between 70% and 80% of the students at the university would first try to purchase used books. What is the margin of error?

▸ 10%

▸ 75%

▸ 25%

▸ 5%

Question 2.

In a survey of 80 football players who committed to play in the Division III CCIW conference, 64 said that they would work out in their high school weight rooms in the summer before college. The margin of error for the survey was 6%. A census of CCIW football players showed that 59% worked out at their high schools. One can conclude that

▸ there must have been an error in the determination of the margin of error.

▸ the sample was an unlikely sample.

▸ the sample was less than forthcoming in their responses to the survey.

▸ the census results are consistent with the confidence interval of the study.
