Textbook Question
Chapter 1.1, Problem 23E
Forming Conclusions. For each of Exercises 21–24, use the information about the confidence interval to answer the given question.
23. Feeling Tired. A USA Today report stated a survey of 22,000 high school students found that 39% of them reported being tired on most school days. The margin of error is less than 0.1 percentage point. Can we safely conclude that fewer than half of all students say they are tired on most days?
