Q$1[9$ pts$]$ Individuals and variable type 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$).$ 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.
