Julian Jordan STAT 4210 Assignment 3 2b.) ŷ = 96.307 + 0.026x 1 2c.) RMSE = 0.712, R 2 = 0.064 2d.) The slope for this model can be interpreted as follows: If the heart rate for an individual were to be 0, then the predicted body temperature of that individual would be approximately 96 degrees. This is an unrealistic interpretation. 3.) 3a.) ŷ = 96.251 + 0.0252x 1 + 0.269x 2 3b.) The R 2 value of 0.098 means that 9.8 percent of the variability in body temperature is explained by the model. The Root Mean Square Error value of 0.702 means that there is a high rate of error between the actual body temperatures of the individuals and the predicted body temperature made by the model.

### 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.

• 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.

• 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.
