I need some help with questions- with R
The iris dataset (included with R) contains four measurements for 150 flowers representing three species of iris (Irissetosa, versicolor andvirginica).Seelink for photos of the three species: https://www.statlab-heidelberg.de/data/iris
- Inspect theIris datain R.
- UsethesummarycodeinRtoperformdescriptiveanalysis.PasteSummarystatisticsinyourreport.
- Draw a scatter plot, for petal length vs petal width.
- UsePairscommandforcreatingpairwisescatterplot forallvariablesinthedataset.
- Find all possible correlations between quantitative variables. Which variables appear to be highly correlated? For the following questions, assume the 150 flowers in your dataset form your sample space.
- What is the probability that the iris has a sepal length greater than 5.8?
- 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?
- What is the average petal length of allsetosaflowers with asepal length greater than 5? What is the range?
