Coefficient of Determination If the correlation between height and weight of a large group of people is 0.67, find the coefficient of determination (as a percentage) and explain what it means. Assume that height is the predictor and weight is the response, and assume that the association between height and weight is linear.

and 36 months. If you use
the regression obtained from these ages and predict the height of the child at 21 years,
you might find that the predicted height is 20 feet. What is wrong with the prediction
and the process used?
Coefficient of Determination If the correlation between height and weight of a large
group of people is 0.67, find the coefficient of determination (as a percentage) and
explain what it means. Assume that height is the predictor and weight is the response,
and assume that the association between height and weight is linear.
Coefficient of Determination Does a correlation of -0.70 or +0.50 give a larger
coefficient of determination? We say that the linear relationship that has the larger
coefficient of determination is more strongly correlated. Which of the values shows a
stronger correlation?
Investing Some investors use a technique called the "Dogs of the Dow" to invest. They
pick several stocks that are performing poorly from the Dow Jones group (which is a
composite of 30 well-known stocks) and invest in these. Explain why these stocks will
probably do better than they have done before.
