Question

Research question: Is the proportion of seniors who are currently taking STAT 200 greater than the proportion of freshmen who are currently taking STAT 200? Which of the following sets of hypotheses should be used to address this research question? Ps = proportion of seniors who are currently taking STAT 200 P_f = proportion of freshmen who are currently taking STAT 200 H_o = p_s - p_f = 0 H_a: p_s - p_f notequalto 0 H_o = p_s - p_f notequalto 0 H_a: p_s - p_f = 0 H_o = p_s - p_f = 0 H_a: p_s - p_f > 0 H_o = p_s - p_f > 0 H_a: p_s - p_f = 0

Explanation / Answer

3.

You can clearly see that in the question a directional claim has been given/or asked

Always remember to take the claim ( that is given in question, or the claim that has been asked inthe question) has to be in the H alternate hypothesis.

So,

Ha: ps - pf > 0
Ho: ps - pf = 0

Hence, answer C is right
