The data show the chest size and weight of several bears. Find
the regression equation, letting chest size be the independent
(x) variable. Then find the best predicted weight of a bear with a
chest size of 50 inches. Is the result close to the actual weight
of 427 pounds? Use a significance level of 0.05.
