Question

5. This exercise involves the Auto data set from ISLR package. (a) To begin, load in the Auto data set. It is part of the ISLR library in R. > library(ISLR) Now the data set is contained in the object Auto. > Auto Read about the data set: > ?Auto How many rows are in this data set? How many columns? (b) Disregard the categorical variables cylinders & origin, and make some pairwise scatterplots of the remaining quantitative predictors in this data set. Describe a couple of strongest variable relationships you notice. (c) Are any of the predictors associated with horsepower? If so, explain the rela- tionship (if you already did so in part (b) - skip this question). (d) Cars of what origin have the largest range in such variables as weight, horsepower and displacement? Comment on those ranges for each origin. (e) How many models in the Auto dataset were produced in year 1980 or later?
