a. Construct a scatterplot. What does the scatterplot suggest about a linear correlation between lengths and weights of bears?
b. Find the value of the linear correlation coefficient and determine whether there is sufficient evidence to support a claim of a linear correlation between lengths of bears and their weights.
c. Letting y represent weights of bears and letting x represent their weights, find the regression equation.
d. Based on the given sample data, what is the best predicted weight of a bear with a length of 72.0 in.?
