"Thirty seniors at Council High School were randomly selected and are asked to report age (in years) and mileage of their primary vehicles. Here are the data that were collected:
R denotes an observation with a large standardized residual
X denotes an observation whose X value gives it large influence.
(a) Describe the relationship between vehicle age and mileage. Include a comment on the strength of association.
(b) Determine the slope of the least-square line. Interpret the slope in the context of this problem.
(c) Determine the intercept of the least-square line. Interpret the intercept in the context of this problem.
(d) Minitab reports that R-sq = 77.0% for these data. Write a sentence that explains the significance of this number
