KidsFeet Parallel Scatterplots by Sex The KidsFeet dataframe contains data collected on 39 fourth grade students in Ann Arbor, MI, in October 1997. Two of the measurements taken on the children was the length, (length), and width, (width), of their longest foot. Based on the scatterplot shown below, there appears to be a positive linear association between the length and width of a fourth grader's biggest foot that holds even when the child's sex is accounted for. One of the following lines of code created everything in the graph below, except for the title and the axis labels. Which one was it?? ( ) xyplot(length~width, groups=sex, data=KidsFeet) ( ) xyplot(width~length,groups=sex,data=KidsFeet) ( ) xyplot(width~length|sex,data=KidsFeet) ( ) xyplot(width~length,groups=sex,data=KidsFeet, auto.key=TRUE) ( ) xyplot(length~width|sex, data=KidsFeet) ( ) xyplot(length~width, data=KidsFeet) ( ) xyplot(length~width, groups=sex, data=KidsFeet, auto.key=TRUE) ( )…
