Attention: These data are different from your previous questions!

Now Lynn takes a different approach. They collect another two samples - GPA from students taking a semester of in-class courses, and then the same students' GPA when they are taking a semester of online courses. The data set is below. They predict that they will find a difference between in-class GPA andonline GPA for the same students.

Student	In Class GPA	Online GPA
Amy	4.0	3.5
Brad	3.5	2.2
Caroline	3.7	2.0
Dan	3.5	3.5
Emily	3.6	3.3
Frank	3.2	3.2
George	3.3	2.1

What is the difference between mean in-class GPA and mean online GPA for the same students? Round your answer to two decimal places.
