2. Open up the Iris data file and a. calculate the average sepal length, sepal width, petal length, and petal width of all the flowers in the dataset for each of the three species. b. find the maximum petal length for each of the three species. (Hint: To find a maximum, you need to store the previous best-seen value.) 2.
