Determine the P value for this hypothesis test. P value =_. Round to three decimal places as needed.

 

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 guidance). In the spring
semester, he taught 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 on their final exam. Complete parts (a) through (e) below.
