The famous iris dataset (the first sheet of the spreadsheet linked above) was first published in Fisher. The dataset contains 50 samples from 3 iris species: setosa, virginia, and versicolor. Fo measured, all in cm: sepal length, sepal width, petal length, and petal width. What is the equation for the least square regression line where the independent or predictor va and the dependent or response variable is petal width for iris virginica? Ex: 1.234 Ex: 1.234 C+ What is the predicted petal width for iris virginica for a flower with a petal length of cm 6.61 Ex: 5.12
