A professor wanted to determine whether an online homework system improved scores on a final exam, In the fall semester, he taught a class using the online homework system (which meant students did their homework online and received instant feedback about their answers along with helpful quidance). In the spring semester, he taght a class without the homework system (which meant students were responsible for doing their homework the old-fashioned way - paper and pencil). The professor made sure to teach the two courses identically (same text, syllabus, tests, meeting time, meeting location, and so on). The table summarizes the results of the two classes or their final exam. Complete parts (a) through (e) below. Click the icon to view the table. (e) Did the students perform better on the final exam in the fall semester? Use an a= 0.10 level of significance. State the null and alternative hypotheses. O B. Ho: Hal= Pspring O A. Ho: Hral= Hspring H: Ptal Hspring H: Prall>Pspring O D. Ho: Ptal > Pspring OC. Ho: Htal= Hspring H: Ptall

(e) Did the students perform better on the final exam in the fall semester? Use an a= 0.10 level of significance. State the null and alternative hypotheses
O B. Ho: Pral=Pspring
O A. Ho: Htal= Hspring
H1: Htal Hspring
H: Prall > Hspring
O C. Ho: Hfal= Hspring
O D. Ho: Plal>Hspring
H: Hfal < Hspring
H Pial < Hspring
Determine the P-value for this hypothesis test.
P-value = (Round to three decimal places as needed.)
