## Problem $2$

"Consider the "mtcars' data set. Use "Nggplot$()"*$ to make a scatterplot of $"$mpg

y$-$axis$)$ modeled by horsepower $\text{'}$hp$\text{'}($on x$-$axis$).$ Create facets by the number of

cylinders $(cy{l}^{\text{'}})$ along the horizontal axis, with no splits vertically. You should

have $3$ dotplots for $4$ cylinders $($on the left$),6$ cylinders $($in the middle$),$ and $8$

cylinders $($on the right$).$ You can use facet$\_$grid$(.$ cyl$)$ for this. Explain what

patterns or trends you see in your plot.$*$
