1. A statistics professor would like to test the effectiveness of his teaching. A random sample of n = 5
students is selected from his class, and these students are administered a standardized test on statistics. For
the general population of students, the mean on this standardized test is u = 10. Is there sufficient evidence
to conclude that this professor's students score better than average? The data are as follows:
