Iris is a flowering plant genus of $310$ accepted species with showy flowers. In the following dataset, it consists of $3$ different types of irises and petal length $($cm$).$

Petal.Length Species $1\mathrm{.}4$ setosa $1\mathrm{.}4$ setosa $1\mathrm{.}3$ setosa $1\mathrm{.}5$ setosa $1\mathrm{.}4$ setosa $1\mathrm{.}7$ setosa $4\mathrm{.}7$ versicolor $4\mathrm{.}9$ versicolor $4\mathrm{.}0$ versicolor $4\mathrm{.}6$ versicolor $4\mathrm{.}5$ versicolor $6\mathrm{.}0$ virginica $5\mathrm{.}1$ virginica $5\mathrm{.}9$ virginica $5\mathrm{.}8$ virginica

For easy copying, the values of each variable:

Petal.Length: $1\mathrm{.}4,1\mathrm{.}4,1\mathrm{.}3,1\mathrm{.}5,1\mathrm{.}4,1\mathrm{.}7,4\mathrm{.}7,4\mathrm{.}9,4\mathrm{.}0,4\mathrm{.}6,4\mathrm{.}5,6\mathrm{.}0,5\mathrm{.}1,5\mathrm{.}9,5\mathrm{.}8$

Species: setosa, setosa, setosa, setosa, setosa, setosa, versicolor, versicolor, versicolor, versicolor, versicolor, virginica, virginica, virginica, virginica

$($a$)[1$ pt$]$ What are the individuals in this dataset?

$($b$)[2$ pts$]$ For two variables in this dataset, identify their type.

$($c$)[2$ pts$]$ Choose an appropriate Shiny app to produce two different graphs for the variable,

$$Species$.$ Basically, you could copy and paste the Species value in the right Shiny app, then

screenshot the output, this will be your answer to this part.

$($d$)[3\mathrm{.}5$ pts$]$ Find the five$-$number $($Min$,$ Q$1,$ Median, Q$3,$ Max$),$ mean and sample standard

deviation for variable, $$Petal$.$Length$.$ For this part, again, choose an appropriate Shiny app to

produce all the required summary statistics.

$($e$)[$o$\mathrm{.}5$ pt$]$ List one graph that is appropriate for the variable, $$Pental$.$Length$($you don$$t need to

produce the graph, just give the name of graph that is suitable for this variable$).$
