Twо fоrmаts fоr а new series of sociаl studies textbooks are being considered. The first has questions at the beginning of each section of the book. The second has the same questions at the end of each section. A small preliminary study was undertaken by the publisher to examine the preferences of teachers. Twenty-four teachers were randomly selected from the list of all teachers in the city of Chicago. The publisher met with these teachers. Samples of both formats were given to the teachers. After examining both types of textbook, the teachers identified the format they preferred. Eighteen of the 24 teachers favored questions at the beginning. The outcome of interest to the publisher was the proportion of teachers who favored questions at the beginning. Let p represent the population proportion of teachers who favor questions at the beginning. Why is Ho: p = 0.5 a useful hypothesis to test in this situation?

Twо methоds оf teаching stаtistics аre to be compared. Method A (experimental) involves the use of computerized instruction, with each student using the computer whenever they please for as long as they please. Method B (traditional) involves lectures, textbook, and study manuals. From the 32 students who enrolled for this course, 13 were randomly assigned to Method A and 19 to Method B. At the end of the semester, a valid achievement test was given to the students in both groups. The results of this study will be used to help decide if Method A should be adopted in place of Method B. The following summary statistics were obtained: Method A (Experimental) Method B (Traditional) n 13 19 Mean 57 50 SD 10 10 Assume the experiment described above was modified as follows: A preliminary assessment of each student's math ability was made. 16 pairs of students were formed. Both members of a pair had very similar scores on the preliminary assessment. One member of of each pair was randomly assigned to Method A (traditional), and the other to Method B (experimental). Why would the experimenter go through this laborious process of creating matched pairs?
