Use the following to answer the questions below:

There are 24 students enrolled in an introductory statistics class at a small university. As an in-class exercise the students were asked how many hours of television they watch each week. Their responses, broken down by gender, are summarized in the provided table. Assume that the students enrolled in the statistics class are representative of all students at the university.

 Male 3 1 12 12 0 4 10 4 5 5 2 10 10 1 = 6 Female 10 3 2 10 3 2 0 1 6 1 5 ​ ​ 2 = 4

Define the appropriate parameter(s) and state the hypotheses for testing if this sample provides evidence that, on average, male students watch more television than female students at this university.

▸ Parameters: μ1 = mean number of hours of television per week for male students and   number of hours of television per week for female students
Hypotheses:  H0 : μ1 > μ2 versus Ha : μ1 = μ2

▸ Parameters: μ1 = mean number of hours of television per week for male students and   number of hours of television per week for female students
Hypotheses:  H0 : μ1 = μ2 versus Ha : μ1 > μ2

▸ Parameters: μ1 = mean number of hours of television per week for male students and   number of hours of television per week for female students
Hypotheses:  H0 : μ1 = μ2 versus Ha : μ1 < μ2

▸ Parameters: μ1 = mean number of hours of television per week for male students and   number of hours of television per week for female students
Hypotheses:  H0 : μ1 < μ2 versus Ha : μ1 = μ2
