In a simple linear regression study between two variables x ( the independent variable) and y (the dependent variable), a random large sample is collected and the coefficient of correlation r = β.98 is calculated. Which of the following conclusion may be made? A.) x and y are almost perfectly correlated, and y increases as x is increased. B.) x and y are moderately correlated, and y increases as x is increased. C.) x and y are almost perfectly correlated, and y decreases as x is increased. D.) x and y are very poorly correlated since r close to -1.
