(g) (2pts) Which of the following statements about correlationr= 0.923 is TRUE? Circle ONE answer. No explanation is required.
(i)The sample SD of the predicted values of the swimming speed isr2= (0.9234)20.85 = 85% of the sample SD of the response (swimming speed).
(ii)The sample variance of the predicted values of the swimming speed isr2= (0.923)20.85 = 85% of the sample variance of the response (swimming speed).
(iii)The sample SD of the residuals is 1r= 10.92347.7% of the sample SD of the response (swimming speed).
(iv)The sample variance of the residuals is 1r= 10.92347.7% of the sample variance of the response (swimming speed).
