(Solved): The above dataset gives the sepal length and width and petal length and width for three species ...



\begin{tabular}{|r|r|r|r|}
\hline \( 7.9 \) & \( 3.8 \) & \( 6.4 \) & 2 virginica \\
\hline \( 6.4 \) & \( 2.8 \) & \( 5.6 \)

The above dataset gives the sepal length and width and petal length and width for three species of flowers: Setosa, Versicolor, and Verginica. 

1. Run an ANOVA test for testing the difference of sepal length between the three species. (Including the summary of data and graphical display)

2. Run an ANOVA test for testing the difference of sepal width between the three species.(Including the summary of data and graphical display)

3. Run an ANOVA test for testing the difference of petal length between the three species.(Including the summary of data and graphical display)

4. Run an ANOVA test for testing the difference of petal width between the three species.(Including the summary of data and graphical display)
