The famous iris dataset $($the first sheet of the spreadsheet linked above$)$ was first published in $1936$ by Ronald

Fisher. The dataset contains $50$ samples from $3$ iris species: setosa, virginia, and versicolor. Four features are

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 variable is sepal

length and the dependent or response variable is sepal width for iris virginica?

hat$(y)=,x+,$ Round $to$ three decimal places.

What is the predicted sepal width for iris virginica for a flower with a sepal length of $5\mathrm{.}48?$

$cm,$ Round to three decimal places.
