Data Were Obtained in a Study of the Oxygen Uptake

Multiple Choice

Data were obtained in a study of the oxygen uptake of 31 middle-aged-males and females while exercising.The researchers were interested in the use of a variety of variables as predictors of Oxygen Uptake.The variables that were measured on the subjects were Age,Weight,the time taken to run a specified distance (Runtime) ,pulse rate at the end of the run (RunPulse) ,their resting pulse rate (RstPulse) ,and their maximum pulse rate during the run (MaxPulse) .The following table from a computer analysis of the data is provided (with some entries deleted and replaced by _**) . The degrees of freedom for model (DFM) and total (DFT) are

A) DFM = 5 and DFT = 31.
B) DFM = 4 and DFT = 30.
C) DFM = 6 and DFT = 31.
D) DFM = 6 and DFT = 30.
E) DFM = 5 and DFT = 30.
