I've some question of R code want a answer -- 2

The iris dataset (included with R) contains four measurements for 150 flowers representing three species of iris (iris setosa, versicolor and virginica). Select the links to be taken to the data of the three species and some notes on classification based on sepal area versus petal area.

1. Inspect the iris data in R.
2. Use the summary code in R to perform descriptive analysis. Paste summary statistics into your report.
3. Draw a scatter plot for petal length vs petal width.
4. Use pairs command for creating pairwise scatter plot for all variables in the data set.
5. Find all possible correlation between quantitative variables.
6. What is the probability that the iris has a sepal length greater than 5.8?
7. If we know that the iris is of the virginica species, what is the probability that the iris has a sepal length greater than 5.8?
8. What is the average petal length of all setosa flowers with a sepal length greater than 5? What is the range?
i will tell detail in msg.
