A nursing school professor is interested in determining how her college students compare to the national average when it comes to the Final Practicum Exam. The exam has a µ = 100 and σ = 20. There has been no evidence to suggest whether those seniors score better or worse than the national average and she is curious as to how her class (N=17) compares.
