Do undergraduates sleep less than graduate students?

He surveyed random samples of 75 undergraduate students and 50 graduate students. Subjects reported the hours they sleep in a typical night.

For this hypothesis test, he defined the population means as follows:

  • LaTeX: mu_1
    ?

    1 is the mean number of hours undergraduate students sleep in a typical night.

  • LaTeX: mu_2
    ?

    2 is the mean number of hours graduate students sleep in a typical night.
