Abstract
The purpose of this study is to determine what the students at North Olmsted High School prefer: books or movies.
To determine this, a simple random sample of seventy two students was obtained from a list of all the high school students attending North Olmsted High School. Surveys were sent out to these students and fifty five completed surveys were returned.
From the results, the average approval score for books and movies was computed for each student using Minitab.
These data values were used to conduct a paired t-test with the null hypothesis being that the true mean difference between the approval score for books and the approval score for movies is zero. The alternative hypothesis was that the average approval score for books was less than that for movies.
After the hypothesis test was conducted in Minitab, we were able to reject the null hypothesis. The alternative hypothesis was accepted. From this, we can conclude that the students at North Olmsted High School prefer movies to books.
However, here is a disclaimer: the study was far from flawless. There were many confounding variables, which included the student’s grade. There was undercoverage and nonresponse bias involved. Therefore, the results of this study must be accepted cautiously, paying attention to the various biases involved.
