In a sample of 171 students at an Australian university that introduced the use of plagiarism-detection software in a number of courses, 58 students indicated a belief that such software unfairly targets students ("Student and Staff Perceptions of the Effectiveness of Plagiarism Detection Software," Australian J. of Educ. Tech., 2008: 222-240). Does this suggest that a majority of students at the university do not share this belief? Test appropriate hypotheses.
