Prediction- Results will indicate that height will have the highest R2. Methods The lab manual was used in determination of vital capacity (Leady, 2008). There was a change in procedure dealing with the number of plastic bags used. Instead of reusing four bags, all the students had their own bag. Results There was 22 students who participated in determining their vital capacity. The raw data consists of all of the students data. Data tables 1-3d represent the results performed. Then Figures 1-4 represents the graphic description of data tables 3a-3d. Figure 4, represents the corresponding R2 values for data tables 3a-3d.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

Kiran Temple University Fox School of Business ‘17, Course Hero Intern

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

Dana University of Pennsylvania ‘17, Course Hero Intern

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
