1. Matched pairs t-test: Using SPSS only, perform the following analysis using the data shown below: A calculus professor wanted to know if scores on a final exam differed between students who took classes virtually (via Zoom) compared to students who took class in person. Twenty students matched on GPA, year in school, and academic major were randomly selected from all the students taking calculus that year. One student from each pair was randomly assigned to either the Virtual Class or In-person Class. At the end of the semester, students' final exam scores were recorded, and the teaching methods were compared. Show the output (paired samples test box) for this test.

a.What are the hypotheses for this study (in words and symbols)?

b.Print out Paired Samples Test box.What is the t-test value for this comparison?What is the correlation between these two variables?

c.Write up the results.

Note: n = 10 and the mean difference = 3.00.
