Reducing Errors in Spelling A ninth-grade teacher wishes to see if a new spelling program will reduce the spelling errors in his students writing. The number of spelling errors made by the students in a five-page report before the program is shown. Then the number of spelling errors made by students in a five-page report after the program is shown. At alpha = 0.05 (a=0.05) did the program work?
Before. 8---3---10---5---9---11---12
After. 6---4----8----1---4---7---11---

Do students reduce study time in classes where they achieve a
higher midterm score? In a Journal of Economic Education article
(Winter, 2005), Gregory Krohn and Catherine O’Connor studied
student effort and performance in class over a semester. In an
intermediate macroeconomics course, they found that “students
respond to higher midterm scores by reducing the number of hours
they subsequently allocate to studying for the course”. Suppose
that a random sample of n=8 students who performed well on the
midterm...
