Specifically, the professor wants to test if the average number of hours that seniors study is greater than the average number of hours that freshmen study. If the seniors are considered group 1 and the freshmen are considered group 2, what are the hypotheses for this scenario?

Question 2 options:

1)

H_O: _{1 2}

H_A: ₁< ₂

2)

H_O: ₁< ₂

H_A: _{1 2}

3)

H_O: _{1 2}

H_A: ₁> ₂

4)

H_O: ₁> ₂

H_A: _{1 2}

5)

H_O: ₁= ₂

H_A: _{1 2}
