The IQR for average female marathon pace is 13, which means that the middle 50% of average marathon paces for females fall within 13 minutes of each other. Females who ran the marathon were much more consistent in their times then the males who ran it. 2 Variable LSRL: ŷ =654.914-3.286x ŷ : predicted time for male in minutes x: age in years R: r=-0.618 Slope: On average, for every additional year of age, the predicted time for males went down by 3.286 minutes. Y-Intercept: At 0 years of age, the predicted time for males is about 654.914 minutes. R 2 : 38.244% of the variation in time can be explained by the linear model relating age to time. DUF’s : There is a strong, negative, and linear association between age in years and time in minutes for females in a marathon. There does not appear to be any unusual features. Residual Plot: This is no the best model because we can see that the residual plot has a pattern and it isn’t random.

Now, we can look at the females: LSRL: ŷ=808.982 -7.086x ŷ: predicted time for a female in minutes x: age in years R : r=-0.659 Slope: On average, for every additional year of age, the predicted time for females went down by 7.086 minutes. Y-Intercept: At 0 years of age, the predicted time for females is about 808.982 minutes. R 2 : 43.405% DUF’s : There is a strong, negative, and linear association between age in years and time in minutes for females in a marathon. There does not appear to be any unusual features.

### 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.
