Consider the $`$mtcars$`$ dataset. Create a graph with all of the following.

a$.$ A bar graph with cylinders as a factor on the x$-$axis and the count on the y$-$axis

b$.$ Make the graph into a stacked bar graph using the $`$vs$`$ variable to fill in the bars.

c$.$ Change both axis labels to something that makes more sense.

d$.$ Add a meaningful title.

$**$Extra Point$**.$ Change the title of the legend to say $`$V Shaped Cylinder$`$

$**$Extra Point$**.$ Change the legend labels so $0=`$V$-$shaped$`$ and $1=`$Straight$`$

$2.$ Using the table$1$ package, create a table that shows descriptive information about the

dep$\_$delay, arr$\_$delay and air$\_$time variables from the $$FLIGHTS$\_$DT$$ dataset. Split these

descriptive results by the airport $($origin$).$ In addition, make sure the table includes an overall

column.

$3.$ Using the $`$EXPECTED$`$ and $`$ENROLLED$`$ datasets, create a line graph that includes one line with

the expected enrollment and one line with the actual enrollment.

a$.$ In addition to the lines, create points that represent each enrollment point for both the

expected and enrolled data.

i$.$ The expected enrollment line should be dashed and blue. The expected

enrollment points should be blue.

ii$.$ The actual enrolled line should be solid and red. The actual enrolled points

should be red.

b$.$ Make sure there are meaningful labels and a meaningful title. Make sure all labels are

meaningful and add meaningful title.
