Statistical Literacyr Suppose the scatter diagram of a random sample of data pairs (X, 3;] shows no linear relationship between x and 3r. Do you expect the value of the sample correlation coefficient r to be close to 1, 1, or U'? Statistical Literacyr What does it mean to say that the sample correlation coefficient r is significant? Statistical Literacyr When using the leastsquares line for prediction, are results usuallyr more reliable fer extrapolation or interpolation? Statistical Literacyr Suppose that for a: = 31 the predicted value is g} = 6. The data pair {3, 8} is part cf the sample data. What is the value of the residual for :1: = 3
