Data from n = 19 female wild bears of varying ages are used to estimate an equation for estimating Y= weight from X = neck circumference. One of the observations has (x, y) = (10.5, 140). Below is a plot of the data and regression results for an analysis when this observation is included in the dataset and when it is deleted from the dataset.
